Some action group headings greyed out

any thoughts on this?

I found this thread from last year and it appears the same problem has reoccured in 2.2.5? I have one project in which the action groups are bold, as they should be. I have other action groups in different projects with identical settings pictured above that have greyed-out headings.

it’s kind of counter-intuitive to have greyed-out action headings, wouldn’t you think? I sent an email on this already, but wondered if anyone else had the problem/found a solution.
