How i can remove that?

I the same problem and nobody has my username and since there is clearly a space it shouldn’t be the same. There account Is dead nobody uses it.

Change your tag to something no one else has.

The system doesn't see things like spaces, as making a gamertag unique. So since there is another account with that tag, you'll get the suffix. Gamertags are also in use on other Microsoft services, so even if it hasn't been active on Xbox, it may be in use somewhere else.
