Hello,
my thumbnails on a preview aren't aligned. Some have higher width and some shorter. If i click to View image in new tab, tab open with very large image. I didn't edit anything on View, it's all default.
If i change size="product-thumbnail" nothing happens no matter what size i put in there.
What can cause such behavior ?

This is filter editor

[wpv-filter-start hide="false"]
[wpv-filter-controls]
	[wpv-pagination]
<div class="pagination">
  [wpv-pager-nav-links]
  [wpv-pager-prev-page]
  	[wpml-string context="wpv-views"]Previous[/wpml-string]
  [/wpv-pager-prev-page]
  [wpv-pager-next-page]
  	[wpml-string context="wpv-views"]Next[/wpml-string]
  [/wpv-pager-next-page]
</div>
[/wpv-pagination]
[/wpv-filter-controls]
[wpv-filter-end]

and Loop output

[wpv-layout-start]
[wpv-items-found]
<!-- wpv-loop-start -->
      <wpv-loop wrap="4" pad="true">
         [wpv-item index=1]
            <div class="row">
              <div class="col-sm-3">
                [wpv-post-body view_template="Ad format - grid"]
              </div>
         [wpv-item index=other]
            <div class="col-sm-3">
              [wpv-post-body view_template="Ad format - grid"]
             </div>
         [wpv-item index=4]
             <div class="col-sm-3">
            	[wpv-post-body view_template="Ad format - grid"]
             </div>
        </div>
         [wpv-item index=pad]
        <div class="col-sm-3"></div>
         [wpv-item index=pad-last]
              <div class="col-sm-3"></div>
        	</div>
      </wpv-loop>

It's fixed by restarting everything. Still unsure what cause it...
