Iv looked on a few of my characters and the add item tab or manage equipment and I go to wonderous items it says none found. Iv tried checking and checking all the boxes magic common proficient but they wont come up and it's only the wonderous items all other tabs work fine.

I've just observed the same bug on my characters. 

Same here.

Happening here too..... 

Yeah, it’s a recently introduced bug. You can search by name of the item in the character sheet and find them, just not with the filter on. If you want to see all the wondrous items, go to Game Rules>magic items. You can filter for wondrous items there.

Thank you for the work-around. 

Ya thanks for the work around but is it currently being fixed? Does anyone know?

I would assume it is at least on the list of bugs to be fixed.  It’s been reported multiple times in multiple threads, and DDB staff are usually on top of those reports.  A moderator was one of the commenters on at least one thread about this, so I would presume they have passed it on.  I’ve not seen staff comment directly, but they don’t always. It was asked about on the March 14 development update; Badeye didn’t know about it, but given DDB’s responsiveness, I would be pretty confident it reached the right ears.
