The Banking section lets you view and edit the downloaded transactions from your financial institution. That's the place I want to categorize my transactions and Add them to the register.  The problem is that there is a major bug in the code with the pulldown list of categories when I edit a transaction before clicking Add. It never shows the full list of categories: sometimes it shows a single category, sometimes it shows suggested categories and below that a subset of categories. Sometimes is shows the sub-categories for a selected category but when I try to scroll to the one I want, it disappears from the list. They are filtered weirdly with no rhyme or reason. I have to type in the category I want if I want to change it, whether set by default or by rule.

Compare that with showing the category list when editing a transaction in the Register: the full list is shown and the one already chosen is scrolled to. It's easy to move up and down around the selected one and chose a new one. QBO: please make the pulldowns behave the same no matter where you edit the category in a transaction! I'm tired of manually typing the category if it's not the one I want.
