Not sure if this question was ever resolved but I had the same issue. I resolved it by ensuring that in the bank deposit window where it says "show payments for this division" that the drop down is assigned to the location that you want for it show up under. Its very strange because it gives you the impression that the drop down filters your transactions but it actually fixes the issue. I've included two screenshots below. The first shows what causes it to show up unspecified, the second shows that when assigned to a division, it then resolves it, at least for me.
