Could you do us a favor in helping us check which maps are those? I've linked this thread in our next wz edit fix.
We're aware of that. Apparently it affected some other non-FM maps as well. We'll be making a fix in the next patch.
All maps of Orbis and Helios Tower are bugged. Spoiler < is a character entity reference for the < character in HTML. While Eos Tower use (1st floor) instead of <1st floor> for example, it dose not have this issue. @Kai
