Author not mapped to Bitbucket user

Bitbucket stopped recognizing me as a user after I changed my Atlassian password.
It does not really create problems for me, everything I need works, but my new commits are no longer marked by my avatar (see https://bitbucket.org/sergworks/tforge/commits/all ). When I click on my name after question mark I see this:

Unmapped user

This user is not recognised in Bitbucket.

sergworks

Create an alias in your repository administration.

But it does not make sense to me create an alias from sergworks to sergworks.
