Bootstrap 4 dropdown menu translate3d() incorrect position

Have a multiple bootstrap 4.4.1 dropdown menus, each in a col which is working fine EXCEPT for the calculated position. HTML col Example

<div class="container">
  <div class="row">
    <div class="col">
      <div class="dropdown">
        <a class="btn btn-secondary dropdown-toggle" href="#" role="button" id="snl-68778" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" tabindex="0"><div class="btn-txt">TEXT</div><div class="chevron-wrapper"><svg class="chevron"><use xlink:href="/img/chevron-white.svg#chevron"></use></svg></div></a>

        <div class="dropdown-menu" aria-labelledby="snl-68778" style="">
          <a class="dropdown-item" target="_blank" href="#" tabindex="0">Link 1</a>
          <a class="dropdown-item" target="_blank" href="#" tabindex="0">Link 2</a>
          <a class="dropdown-item" target="_blank" href="#" tabindex="0">Link 3</a>
          <a class="dropdown-item" target="_blank" href="#" tabindex="0">Link 4</a>
          <a class="dropdown-item" target="_blank" href="#" tabindex="0">Link 5</a>
        </div>
      </div>
    </div>
   // more columns here
  </div>
</div>

CSS:

.btn,
.dropdown-menu {
    width: 100%;
}
.btn{
  display: inline-block;
  padding: 8px 15px;
  border: none;
  background: #E5392A;
  color: #fff;
  text-align: center;
  font-size: 12px;
  font-weight: 800;
  letter-spacing: 1.5px;
  line-height: 18px;
  text-transform: uppercase;
}
.dropdown-menu{
  margin-top: 0;
  border: 0;
  padding: 0 10px;
  background-color: #211D17;
}
.chevron-wrapper {
  vertical-align: middle;
  display: inline-block;
  width: 36px;
  height: 26px;
  border-left: 1px solid #fff;
  margin-left: calc(100% - 115px);
  padding-left: 10px;
}
.dropdown.show .chevron {
  transform: rotate(90deg);
}
.chevron {
  display: inline-block;
  width: 26px;
  height: 26px;
}

I have 5 columns set up and the problem I have is the position of the dropdown menu in the first and last column:

1st: translate3d(5px, -244px, 0px);

5th: translate3d(-5px, -244px, 0px);

There is a 5px shift to the left/right and I have no idea what is causing that. If I reduce the number of cols to 4, I still get the same shift on the first / last columns.

is there a way of forcing the just first number in the calculated translate3d(5px, -244px, 0px) to always be 0? I tried transform: translateX(0), but that overrode the whole translate3d() setting, not just X

Any ideas
