Normally, using double quotes in a column means 'same as above', not same as to the left. And there's no obvious way to interpret the dash. Same as to the left? Same as to the right? Not written?
May I suggest something simpler and less ambiguous (I have no idea if the following is correct due to the confusion above, but it should be obvious what is intended). Just enter the id3v2 frame name and leave any items blank that will not be written.

Of course, one thing that isn't stated anywhere in the documention is that frames not blessed by Mp3tag in either v2.3 or 2.4 will end up being written as TXXX frames with the Mp3tag field name.
