Marlin: Print resume has 15mm y offset

I installed Marlin 2.0.1 on the CR-10S (stock controller V2.0)- since I swapped out the hot end with a direct drive Bondtech (and the original SW did not allow to adjust the steps per mm and the SW is unstable and clunky anyway).

It works all pretty good except for one thing: When I pause the print or want to do a filament change the print resumes on the precise X position but the Y is shifted (reproducible) 15mm towards the home.

Is this a configuration error on my end?
