Hi!
Yes…this has been an ongoing issue with the new release. Looks like the only way to override previous settings and create new ones (for now) is to turn on Professional Tools and create a Rule Set to apply in the Multi-Calendar Display (lots of other posts about this issue).
Here is a link to the Community Guide that was created to help Hosts resolve this. It has step-by-step instructions and screen shots.
Let us know if it works for you! It's been working so far 😊
