Berserker, not exactly. Sorry for didn't explain it clearly.

You see, for "name" key, I wrote "Map Rules and Mod Options". Instead of showing these characters, the game shows "Map Rules and Mod OptThis page lets you blablabla...".

Why? Becoz "Map Rules and Mod Options" exceed a unreasonable character limit (which shouldn't be existing) of "name" key and resulted in error - it shows characters from "hint" now. The restriction here is far behind the restriction of the bounding box.

Same happened to "popup". My popup msg exceed a certain restriction so that the last few words overlapped with "name" key of page 5
