Help: username and @username does not connect

Hello,

i have an issue.

Situation:

I have a self hosted gitlab server.
There is an user. [username]
so i can find him after login on
http: // myServer . com/[username]
Now i have a repos.
I can use git, push/pull/etc. with [username]/[password] => all fine…

Here the issue:
When i push, the user in gitlab would be shown as a non existing user called [username].
And when i change something in repos with the browser it is correct connected to my logged in user but with this little “@” before the [username]…

How i can make gitlab understand that this [username] and @[username] is the same user?
Or did i overlook something else?
