Why doesn't the emmet filter work?

Question

Emmet

Good afternoon. When I write code like the following content in sublime text:
.header|c
and open it, the comment is not created, but it turns out something like this: What could be the problem? Plugin reinstalled, no other plugins installed.
.header|<!-- -->

Answer 1

.header+c

<div class="header"></div>
    	<!--  -->

.header>c
<div class="header"><!-- --></div>
