Latch cvars cannot be changed on a TITLEMAP

[Zhs2]

... because a TITLEMAP counts as a game in progress. This hinders end user experience when you're developing a mod with a TITLEMAP (or an addon to one) involving options that shouldn't be able to be changed in the middle of a game session, as when the user enters the options menu they find options that inexplicably can't be changed plus zero feedback on why they can't change them.

Clarification: latch CVARs can be changed, the actual problem is that there is no way to retrieve the pending value from user code - thus, you always see only the current value in the menu, and this is indeed confusing. This likely stems from the fact that latch CVARs were not designed to work with menus in the first place. I believe this issue has been brought up multiple times before, and the only workaround I know of is to use non-latch CVARs instead and implement the "latching" mechanism manually in ZScript, which is exactly what I did in my own project.

That sounds like a lot of extra effort to work around an oversight in the menu code.
