F12 switch and rings

Ok I am wearing small saphs on gold.

In inventory I have 2 huge saphs on gold (both group 2) and 2 huge emme on gold (both group 1) confirmed. I am 1SG so naturally I cannot wear either.

I also had two big saphs on gold, no group in inventory. Inventory had been /sort ed

If I try to swap to group 1 I get Huge emme cannot be equipped x4. If I try to swap to group 2 I get no message at all.
