Sparkasse Geroge Login

I have a problem with the following page: https://login.sparkasse.at/sts/oauth/au ... orgeclient
The auto-filling of the password works fine, but the username is not working. The type of the username field is "number". I also tried to save the login credentials using the "Save All Entered Data" function of the LastPass extension in Google Chrome and Mozilla Firefox. But the username is still not saved correctly.
Any solutions or my problem?
