Wrong widget profile name

Hello,

Thanks for this plugin.

I noticed that the pie register login widget kept using the same profile name for every user signed in. It displays the right avatar for the user but the name remains the same for everyone. The name displayed is that of one of the users.
Any idea why this is happening and what can be done?

I also notice that sometimes, I have to try to sign in twice or more before it is successful. I initially get an error message that something went wrong.

Thank you
