Hi Marc,
I saw your post here now. In your email you said it "never showed up". I thought you meant you had posted it days ago. I didn't show up in these three hours because I have to approve all posts first to prevent spam.
Anyway, you can change the order of these calendars under "Settings > Visibility/Download > Sort calendars" (in the menu of that screen). 🙂
Please don't hesitate to contact me again if you have further questions!
Kind regards
Dominique
