Why I am seeing this message?

Why I am seeing this message:
Any modification done here will not impact the currently loaded timeline as they are being overridden by timeline settings.

This project was created in Resolve 19 and I don't see that message in Resolve 19 but only in Resolve 20.
I need to change the color space for this project, so any idea how to fix that?
