Some strings are all caps when they should be sentence case, and some strings are sentence case when they should be all caps.

Why is the MCM doing this to me? How do I get the strings to print correctly?

Papyrus caches all strings in a case-insensitive form. One work-around is to append a space on the end of your string. (Of course if some other mod did the same thing to get the other kind of case the player will still get the wrong thing.)

The best solution is to use the SKSE localization feature. See the Localization section of the https://github.com/schlangster/skyui/wiki/MCM-Advanced-Features documentation page.

So that's what the dollar signs were doing in ski_configmenu.psc! Thank you!
