Possible Bug?

Hey everyone, I have noticed that when I print with polycarbonate with orca slicer the first print will ALWAYS push the nozzle into the build plate and scratch everywhere it tries to extrude filament. This only happens when printing polycarbonate and only the first print. if I cancel the print then try again it doesnt happen again.

This is on my creality K2 Plus and when using creality print this does not happen at all. I have thoroughly compared settings and made sure they are the same and the issue only happens when using orca slicer with polycarbonate on the first print after a shutdown.

Wanted to reach out and see if anyone else has had weird issues like this with orca and see if its just me and I need to find a hidden setting somewhere or if its a possible bug with Orca.

just for clarification I have also tried with PLA, PETG, ASA, ABS, and TPU, the issue does not persist with any other filament.
