I had the same problem and in my case the fix was simple (even though I had to debug ALL the plugin code to realize it had nothing to do with it). I have different container IDs for the post and custom type listings. #listing for posts and #content in my archive-type.php template.
So I added this selector values in the plugin admin and both work now.
- Content CSS Selector: #listing,#content
- Post CSS Selector: #listing .cell,#content .cell
Hope this helps other as well.
