Cannot convert post category to 'Feature and Improvement request'

When attempting to convert a ‘General Questions’ post to a ‘Feature and Improvement Request’ type, this message is encountered:

It seems some types can be converted to, but I have not comprehensively tested which.

Someone ought to QA the options from the perspective of a general user and ensure the options that can or cannot be selected.

Furthermore, I appear to be able to select ‘Announcements and News’ - which sounds very much like an option I should not have access to post as, especially given the false security sense a post under that category could pose.
