UPDATE
It is the machine setting in the upper left. It apparently reverted to an older version that I copied. Once changing that, the issue was resolved.
This is not prime lines but calibration lines for pressure advance(dynamic flow calibration) , just turn it off , and use the new method Bambu studio provides or use Orca slicer so calibrate once , instead of everytime losing 3 minutes and plate space. Calibration is per filament type and brand usually color variations does not matter
