Color-coding disappears in rules list.
I just transferred to a new iMac with Catalina and notice that when I open rules to edit my color-coding for emails, none of the rules in the list have their colored background. Normally I would see the list of rules with the colors I have set for each rule, but now I don't see the color. When I click to edit one of the rules, all the colors in the list return. Why is this and how to I fix it so it works the way it used to work?
