All Items Appearing in Collections

Hi there,
I have a couple of collections on my Omeka site. Everything is fine except when you press ‘View the Items in the Collection’ all items appear, even ones that aren’t in that collection which kind of defeats the purpose of the collection. I wonder can anybody help. The website is www.huarchive.co
thanks,
Greg

Do you have avant search installed? There was a similar issue earlier this year

Hi there,
I did! I deactivated Avant Search and it worked properly.
thanks,
Greg

We also resolved it by deactivating Avant Search. Thank you!
