Horizontal banding exported form Photo AI 3.0.4

After exporting CR£ raw file back to LRc from Photo AI I am getting banding on the tiff file. It is most noticeable when increasing shadow detail.
Further to above if I use “file, Plug-in extras, process with Photo AI” the banding doesn’t happen.

Steps to reproduce issue:

  1. Step 1 - Export raw file from LRC to photo ai
  2. Step 2 - Process image in Photo AI, autopilot settings
  3. Step 3 - export back to LRc and increase shadow detail. Banding appears as horizontal lines and square blocks. Very strange.
