my launcher saves my email incorrectly

If I open my minecraft launcher and try to play online it says im offline even though I have internet so I go check my account and the email adress is f7cb92cd845cdb4abba0f3d2184704ba and there is no password so I have to log out fill in my email and password then it works but if I log out or close the launcher again the email is reset to f7cb92cd845cdb4abba0f3d2184704ba and there is no password again which is very annoying since I have 2 accounts which i both use even though for some reason this only affects my main account
