Problems LrC - DXO PL 6


ive notice some problems within my workflow with Lightroom an PL6

MacBook Pro M1 Max
macOS: Ventura 13.4.1
Lightroom Classic: 12.4
DXO Photolab 6.8
Sony Alpha 7 IV
I’m doing mostly noicereduction

I mainly do noise reduction with DXO PL6. My workflow is as follows: I develop my images in Lightroom and then transfer them to DXO PL6 using the add-on module manager.
In DXO I have the following settings:

When I now export the image back to Lightroom, I sometimes have very unattractive artefacts in the brightness transitions. See pictures.

Does anyone else have this problem?
Thanks a lot.
