WTR (way to reproduce an issue):

Step 1: Go to Champions Index

Step 2: Click on a champion who has any stun set item

Step 3: Click filter, select Equipped on the preselects

Step 4: Scroll down to where the Stun set would be (normally between Destroy and Toxic sets)

Description:

The Stun set item group does not show up at all, eventhough I had previously equiped a few items on a Champion but now I can no longer see any other items for this set to add.
