Bug report: VRChat filter not showing products with vrchat-asset tag

Store: ichigodaiduku
When I check "VRChat" under Social VR Platforms filter on my shop page, my VRChat-related products (e.g. Bolero series) disappear from results — even though they have "vrchat-asset" tag set in Discovery Tags.

I couldn't find a dedicated "Platform" field separate from Discovery Tags / Community Tagging in the product editor (checked all 4 tabs: Setup & Versions, Page Content, Files & Content, Publishing & Marketing).

Is there a specific field I need to set for the Social VR Platforms filter to pick up my products?
