So recently i have changed my name from xSUMMERx, to SUMMERmusic. However, this issue causes compatibility issues with geometry dash, thinking that the old and new names are different people. I have messaged Tom Fulp for a name revert. Hopefully he responds :)
Worst case scenario, you have to wait 28 days until i can change my name again

I am 99% certain that the issues is on the side of GD and that NG staff cannot do anything about it.
You should contact administrative staff within the GD-community to resolve the issue.
SUMMERmusic
If I wanted to get re-whitelisted under my new name then yes, but i asked him to revert it to the original
