If you switch the message list theme, all text in the message list disappears. (Subject, Date, Foldings, etc.). Everything else remains functional, and the "Clickable Status" is shown. Reproducible: Always
Version is 4.13.2 (not in list). ArchLinux fully updated
I don't have it. When I switch to "smart" theme I don't have column title, but "smart + clickable status" I have. But it's a theme settings so you can readd it in settings.
