2021 Volvo P02CE00 Clinder 2 fuel injector offset learning at min limit

2021 D13 throwing this code. See pics below for compression test and cylinder balancing results with ptt. Volvo dealer replaced injectors 2,4,6. Still getting codes after injector replacement. I updated software in ecm, no codes for a week, then started getting codes again. Took back to Volvo dealer, they replaced injectors 1,3,5. They said cylinder balance test is still showing under fueling. Volvo dealer says replace head. Truck starts and runs perfectly. Any other cases with this?
