Problem when changing project settings in DR Studio 17.1.1

Hello,
After updating this week to DR 17.0 and 17.1.1-Studio Version (from DR 16 studio version) I get into major problems every time I change the project settings. What happens is that every little change in the project settings (e.g. fairlight target loudness level or proxy media resolution...) will cause my color grading to change immediately (both in the viewer and in the rendered video). And these changes in the project settings cannot be fixed with the "undo"-button.
Has anyone encountered this problem yet and found a solution?
This software bug cost me many business hours today. Therefore, I would be grateful for help.
Best regards,
Valentino
