Xbox Gamertag

I'm trying to change my classic gamertag which is the one you see in games. My classic gamertag got changed and my Xbox One and Xbox App gamertag stayed the same (the Xbox One gamertag is the ones they added with the new gamertag system).

My Xbox One gamertag is different to my in-game gamertag and I want my classic gamertag to be changed. You can only change your classic gamertag on the Xbox One console, I have tried using the other ways and you can only change your Xbox Gamertag, not your
classic gamertag.

The reason I want to change my classic gamertag is that the classic gamertag can be fifteen characters and the Xbox One gamertag can only be 12 characters. If I use the other ways to change my gamertag it limits me to 12 characters and sets both my gamertags
to that.
