Warbank issue - plz help

This is quite unique, but it’s happening:

I have 2 machines. a PC and a mac. I only use the mac on one specific character whose sole purpose is to buy mats to resell later (long story, but I have a spreadsheet on that computer).

The problem comes when I deposit things into his “BANK” and then hit cleanup, things are getting pulled out of the “WARBANK” and combined into the character’s personal bank. This totally defeats what I was trying to do (give this character a lump sum of gold and see if they could turn a profit - it’s now super hard to track cause materials are “randomly” being added to his bank inventory).

I noticed that a few spots in my warbank were empty after a session on that character, but I knew I hadn’t gone into my warbank at all. I went back on, bought one specific mat, and after hitting cleanup in the character’s bank tab, the mats were removed from the warbank to complete a 1000 item stack in his personal bank.

Would be great if it didn’t do this.

Thank you!!

=============================================

Update: OK, not a bug. Happens across PC and Mac. I just never noticed when you hit “clean up bank” it will pull things out of the warbank. So… is there a way to be able to clean up the banks independently of each other without constantly changing the settings on each tab?

I wonder if this is part of what’s happening when my warbank randomly eats items when I swap characters?
I can’t tell what’s missing half the time, just that there’s a weird gap where an item was on the last character.
Some of the missing items that I know specifically are gone, aren’t ending up in anyone’s personal banks though.
