It’s most likely an error with the nozzle height. The PEI plate not heating up enough shouldn’t cause the adhesion in the photo above (and this is not a first layer problem, as the error is not at a uniform height). Additionally, a few lines are very faintly visible on the plate where they shouldn’t be, indicating nozzle height. Make sure that it is easy to move a piece of paper between the nozzle and the PEI plate when adjusting the height, feeling only a very small amount of pressure as you do so.
