In every src or href auto values "$1"$0

I use Atom for a couple of months but recently I notice something strange. Every time I write <img> or <a> and use autocomplete on src or href I have predefined values "$1"$0.

For Example:

<img src="$1"$0>

Of course, I can delete them but is annoying to do it every time. Can you help me what can cause this?
