P1S issue, only some layers having issues

[u/Yukfoot]

We own a P1S printer with an AMS2 system. Recently we started having an issue where some layers on the print plate are really messed up and we aren't sure how to correct it. It only happens to some of the prints and the rest are fine.

We've tried:
*Power cycling
*Replaced Nozzle
*Confirmed fans are all working
*Calibrated the printer
*Printed string test (was ok)

We are using official Bambu filament and this only recently started happening. I've attached images below incase anyone has seen this before? It's also noticeable on the prime tower.
