Hi Achille,

Thank you very much for the question!

We once got a report about this issue on AC23, but due to the lack of reproduction method, we couldn't find out what triggered this. What we know is that, by resetting the Background color with this guide, the background will be reset correctly.

Please let me know if this helps with the issue!

Best regards,

Yes! this worked for me, too, in a project in 24(Solo) which had been updated from 23. It only happened for a couple of sections.
