Same lost access to Zealot Armor, Revan Champion sets. Both unlocked for account.

I seem to have lost access to a few items I already unlocked in collection, unlocked by equipping set and paying with CC to unlock for account. This happened today, Oct 25, 2016. Anyone else having this issue? I still have my set equipped, but I wanted another set for my companion. The set is greyed out in collections, but still have the stamp on it unlocked for account.
