Name change on MSM3 & Discord

I’ve been out of the loop for a while but recently started playing MSM3C again and Uninstalled and downloaded the PlayStore version and logged in with Google. On that profile I have all bikes and really enjoy the game but my username is my old profile name, def1967.
I would like to be able to use my team name HDR_DEFTEK67 which is associated with my Facebook account but that profile doesn’t have all the bikes. Is there a way to fix this?

I’m on Android
