Weird name bug. Need help pls.

[broccoli]

So i just wanted to remove all my aliases because they were prety cringi. So I found this quide on Steam forums that showed how to do it this dude was using this character[pastebin.com] to turn each alias to blank it worked for him so i just did what he did. I renamed myself 5 times then had to wait because of steam renemad myself 2 more times and it stopped working so i have last 3 aliases there and i can't change my name back it just doesn't work. Any tips or should i just ask Steam support?

So I just noticed that he is doing it from steenigs and not from the profile as me is this the problem?
