View Visitor Profile shows wrong User

In the demo app https://demo.matomo.org/ go to visitor section–> click ‘UserId’–> hover over ‘wolframheart’ user -->select ‘visitor profile’ option–> it takes to a profile view where the user name is ‘visitor profile’ where as for other user 9dreamer it is showing the correct profile.

even in my admin panel i see the same behaviour
Why is this happening?

Hi,

I think this is related to this issue, but I am not that up-to-date with UserID myself:
