If you go onto the Manager Timeline you can see for example 14. January 2026 Welcome back - Markus Müller made an Arminia Bielefeld return as Fitness Coach. He was never at the Club before as you can see in his Bio.
Same Problem on the same timeline: It says Old Teammates reunited but they both never played anywhere in the same club or country together.
Often when I hire new Staff they somehow come up in my Manager timeline as if they returned to the club but they never had anything to do with the club before.
