Shoe size filter is broken

[socalwendy]

So I have saved searches for my specific size shoe, but lately when I check that category shoes of all sizes show up. When I start a new search, the shoe size is missing from the filter list, however when I click on a certain shoe size in the results list to filter without using the refine option, all sizes still show up! I've noticed this on the android app, mobile website, and accessing from a desktop.

Please fix this!
