Bank size is global, not per layout. Verify you actually have it set to 10. Sometimes when you mess with the bank size, you need to reboot the FC to make it update as well. I've had to do that once or twice in the past.
It can also change your Bank Inc/Dec Upper Limit values as well, so double check those after changing the bank size. Enter 999 and the editor will automatically select the highest bank for the current bank size setting.
