Android Recyclerview Remove Animation Is Applied To All Items Strange Behaviour

I am using following library to animate items in my recyclerview on removal https://github.com/wasabeef/recyclerview-animators

I am trying to apply slide to right animation to only removed item but for some reason all items in recyclerview disappears first and then animated back to their position strangely. Please watch the following video.

Here is my code its very simple:

   friends_screen_friendlist_recyclerview.itemAnimator = SlideInRightAnimator()
                   friends_screen_friendlist_recyclerview.itemAnimator?.apply {
                        addDuration = 120;
                       removeDuration = 1000;
                        moveDuration = 500;
                        changeDuration = 500;
                   }
    friendItems.removeAt(0)

               friends_screen_friendlist_recyclerview.adapter!!.notifyItemRemoved(0)

Adapter class:

class FriendListAdapter(val items : ArrayList<FriendListItem>, val context: Context,val listener:FriendListListener) : androidx.recyclerview.widget.RecyclerView.Adapter<FriendListViewHolder>(),Filterable {

    var filterItems = ArrayList<FriendListItem>()

    init{
        filterItems = items
    }
    // Gets the number of animals in the list
    override fun getItemCount(): Int {
        return filterItems.size
    }
    override fun getItemViewType(position: Int): Int {
        return position
    }

    override fun getFilter(): Filter {
        return object : Filter() {
            override fun performFiltering(constraint: CharSequence?): FilterResults {
                val charSearch = constraint.toString()
                if (charSearch.isEmpty()) {
                    filterItems = items
                } else {
                    val resultList = ArrayList<FriendListItem>()
                    for (row in items) {
                        if (row.userName.toLowerCase(Locale.ROOT).contains(charSearch.toLowerCase(Locale.ROOT))) {
                            resultList.add(row)
                        }
                    }
                    filterItems = resultList
                }
                val filterResults = FilterResults()
                filterResults.values = filterItems
                return filterResults
            }

            @Suppress("UNCHECKED_CAST")
            override fun publishResults(constraint: CharSequence?, results: FilterResults?) {
                filterItems = results?.values as ArrayList<FriendListItem>
                notifyDataSetChanged()
            }

        }
    }

    // Inflates the item views
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): FriendListViewHolder {
        return FriendListViewHolder(LayoutInflater.from(context).inflate(R.layout.friendlist_item, parent, false))
    }

    // Binds each animal in the ArrayList to a view
    override fun onBindViewHolder(holder: FriendListViewHolder, position: Int) {
        //holder?.profileImage?.background = items[position].profileImage
        holder?.userName?.text = filterItems[position].userName
        holder?.level?.text = "Seviye "+filterItems[position].level

        // do the necessary profilePic checks.
        Picasso.get().load(filterItems[position].profileImage).into(holder?.profileImage, object : Callback {
            override fun onSuccess() {
                listener.onProfilePicLoaded()
            }

            override fun onError(e: Exception?) {
                listener.onProfilePicLoaded() // error but anyway. just tell messages class its loaded so it can show the page.

            }
        })


  if(filterItems[position].gender == 0){
            holder?.gender?.setImageDrawable(ContextCompat.getDrawable(context, R.drawable.male_icon))
        }else{
            holder?.gender?.setImageDrawable(ContextCompat.getDrawable(context, R.drawable.female_icon))
