In consistent Z-Height when using bed mesh compensation. Temperature compensation not used

I re-did all my calibrations of Beacon as per Helge's manual from 1 to 5 https://github.com/HelgeKeck/RatOS/blob/documentation_v2.1/site/docs/configuration/beacon_contact.md#6-first-print-and-fine-tuning.
At part 6 the nozzle is approx. 0.5mm to high, so I babystep to a proper first layer squisch. Enter SAVE_Z_OFFSET in the console. stop the print. Save_config. I see that the output now says:
Beacon model offset has been updated, new value is -0.46781

after restart, the next print is again approx. 0.5 to high and I can repeat this all night. I thought it should report nozzle_expansion_coefficient_multiplier which was then stored in ratos-variables.cfg?
I see the offset stored in printer.cfg

I MUST BE DOING SOMETING WRONG.... But I an (again) clueless....

Solution

So, Only thing that I can think of is that my reference Contact mesh somehow was erroneous.... or something in the other refference files was off. anyway, now I need to redo all the bed meshes But I think I solved it (by accident, that is)
