User alias is not changed everywhere

I commiting to my repositories from two computers and I push some commits before I set up alias for my ssh key. Then I add alias for ssh git key. In commits I saw my bitbucket user, but in overview page it is still only name of git user which create the commit.
I would like to see everywhere my bitbcucket user after that I add alias for my user.

Sorry for my bad english.

Thank you
