I have language set to Engilsh (United States). Should I set it to a different language when trying to modify font sizes?
That language is the problem. When I set my Kindle to eenglish, weird things happen too.
But seriously, it might be the book or font. Looks like it is mobi, so it should work. Some fonts don't like certain sizes. Did you try with different font and different book? And yes most everything needs framework restart.
