When I go to lock items in my inventory, I can only lock eight. When I try to lock a ninth, I get the message saying that I can only lock ten and that I have ten locked. Is anyone else having this problem, or is it just me?

(I did look through the topics for a post on this; hopefully I didn't just miss it!)

I feel so stupid! Apparently I had two items locked that were actually stacks of two. I didn't show a stack until I unlocked them. Sorry to bother you guys!
