Why do topics in this category close after 30-days from creation instead of inactivity?

Many categories in CDAC are configured to close topics after 30 days of inactivity as indicated by this familiar message:

:five_o_clock:This topic will close a month after the last reply.

Other categories have no time-based closure at all.

But topics in this category (“Forge → Adopting Forge from Connect”) automatically close 30 days after creation, regardless of whether they are still active.

Is that a misconfiguration? If so, is there a forum administrator we can tag to fix it?
