Since "have been marked resolved" is the predicate here, it also needs to be translated depending on the number:

• 1 of 1 support thread ... has been marked resolved.
• 2 of 2 support threads ... have been marked resolved.
• 1 of 5 support threads ... has been marked resolved. (This case is currently missing)
• 2 of 5 support threads ... have been marked resolved.

Two approaches to resolve this:

• meta-1750.patch​ moves %s support threads to a separate string, which makes the original one a bit more confusing to translate, but at least it can be translated correctly now.
• meta-1750.2.patch​ simplifies the string so that %s support threads refers to the number of resolved threads (instead of all threads).

I'd prefer meta-1750.2.patch​.
