Filter not working - Load more button not showing

Hello!

I was testing the Portfolio Pro component and I saw some unexpected things.. My filter isn't working as good as I would have expected (some items don't show up) and I do'nt see a 'Load more' button anyware.

Also: using Pagination at filtered content does bring me back to 'all items' (disabling the filter). But I would like to use the 'Load more' option, not the Pagination option.

Many thanks!

Best regards,
Robert
