The difference between auto name or not is that if auto name is set, it creates the marker with the default name of Marker 1, Marker 2, etc. without any further action on your part. If not set, it opens the marker dialog for you to name or press enter to accept what is shown. The marker is created either way. The behavior you are describing in your OP is what happens when you use the enter key (return) on the main keyboard. If you don't have a numeric keypad to the right side with the additional enter key, then an alternate is to click the plus sign in the markers bar while playing.
