Flag colors out of order on Mail 13.0 on Catalina

I have seen this problem with flags disappearing, although it is not always the Red flag which is missing. They all come back if I click on "Flagged" to show all the flagged messages. But if I start selecting individual flag colours, other flags will gradually disappear. I have learned to "reset" the flags by periodically clicking "Flagged" to show all, but it is still annoying.

Same issue over here.

Red was the first flag to display all these years, now somehow in Catalina, orange seems to be the one on the top.

Not only on the sidebar, but also when I click to flag a message

Is there anyway to fix it?

That sounds like a completely separate issue, which is closer to problems such as https://discussions.apple.com/thread/251032977

Following! I miss the Red Flag at the top. Completely ruined my importance flagging... because I think the lower importance flags changed too?!

This is another one of those small, irksome changes that makes you wonder "Why??" I routinely flag my emails, and since switching to Catalina, every time I do, I have this small, irritating urge to do SOMETHING to return the colors to their original-- and much more logical--- order. I'd happily go into Terminal and tinker with a bit of code if that would do the job.

In addition to the sort order my RED Flag will not show at all. all other colors ok but not red.

It is as if RED is not there .
