CMS Load with CMS Filters results in partially hidden collection items

Hello, when using finsweets CMS Load in pair with CMS Filters, sometimes during the filtering there are appear collection items that have opacity set to 0, - - they are clickable, but not visible because of the opacity property, sometime collection items are visible at the top of the list, then some are hidden, and later there are again visible items. Is this is a bug, or are we misconfigured something?
