Git connection to Azure DevOps is not saved and cannot connect

I have a git repo in Azure DevOps. I can connect the first time. The second time it prompts me again with a read only name that is incorrect. I cannot override the name and connect to git.
Details:
Initial connection is OK

However, the user name is wrong

Therefore I cannot log in.
Please help.
