Can you reproduce this problem? What steps will reproduce it?
1.  Unstackable items in my bank,won't stack, even when all the stack options are selected included merge unstackable.

What is the expected output?
All items that are the same should stack

What do you see instead?
Multiple stacks, mostly 1 per stack but sometimes 2.

What version of the addon are you using?
1.7.12

Do you have an error log of what happened? (Please enable the display of Lua errors or install an error-reporting addon to be sure whether an error happens or not.)
No error log.

Please provide any additional information below.
Previously my unstackable items used to stack correctly, but now they don't, primarily this seems to be happening with my Timeless Isles tokens in my bank, but as these are the only unstackable items in my bank that I have more then 1 of, this could just be coincidence.  The problem started with 1.7.11 and was not fixed with 1.7.12.
