Maybe someone can doublecheck, but seriously, do double check, don't go by what you'd expect or what you "heard"!

Also note that when you use the filter, and set it to "Earrings", that the personal earrings no longer show up! (this is actually what made me suspicious, and caused me to investigate)

I know at some point the equipment gained from CQs will be able to be equipped directly to the respective girl instead of taking the slot they used to. My guess is that this is related to what you're reporting.

That's my guess as well, especially since we lately got a bunch of partial updates implemented in preperation for new features.
