Visitors log & app say returning visitor, but visitor profile only shows 1 visit

I got an issue with returning visitors. On the dashboard it says in the mouseover, it’s a returning visitor with 2 visits. But when I open the visitor profile, it says “1 visit” everwhere and I don’t see a second visit.
I need to combine the two screenshots in one image, as I only can embed one image as a new user

Where can I find the second visit?

I’m tracking through the Tracker Proxy, archiving is done through cron was already perfomed for this visitor.
Had another returning visitor one hour later, there everything is showing fine.

Seems similar to this issue: Real-time visitors report returning visitors (icon and mouse hover information), but it is the first visit according to the visitor profile but there is no answer.
