The dropdowns are frustrating to work with. The only way to be assured that you'll get the value you want is to click it in the dropdown. If I am moving quickly and tab into the dropdown, arrow key down to my desired value, and press Enter or Tab, sometimes it keeps the value and sometimes it leaves the field blank. Similar example - tab into the dropdown and key in part of the type that I want (e.g., "int" for Integer), same result - sometimes it keeps it, sometimes it blanks out.
