I was sorting through a shop and purchasing things, but to be safe I was using account search on a few items, they came up as "I cannot find this item anywhere on your account" yet I find out after the fact they were in my gallery or vault...

What gives?

Oh gosh, It was this morning before work. I don't remember exactly I was doing a lot of multitasking.

You need specific items?

Well I don't remember exactly what items they were at this point. Guess you can just lock this up. If it happens to me again I'll have to try to remember to write down every item that it says I don't actually have.
