Item Set Builder Search Bar Bugged [CLIENT]

I've found that the item set builder's search bar for items has been bugged for a while now. Whenever I try to make a new item set for a character, the search bar will simply stop working- the default "Search Items" does not disappear when I type in the box, and items will not get filtered, even when I manually clear the box and try searching for terms then. It appears that this only occurs when I interact with right side of the builder (choosing names for the set/blocks), because upon restarting the client, the search bar will work again UNTIL I interact with another text box.

1. Log In
2. Go to Profile - Item Sets
3. Interact with set name text box
4. Item search bar stops working

This is an extremely frequent issue, as it will happen every time I attempt it, without fail. Screenshot of bugged search bar
