Corrupted trainer names in Pokémon Diamond

[Markitus95]

Hello. I've been using PPRE for about two years to edit many things in Pokémon Diamond for a hack I'm doing, and I've encountered a really annoying issue after editing trainers with PPRE.

Many trainers, including Gardenia, have now their names messed up. Instead of showing their actual name, they display a huge blank space and the player's name. I've checked the text files and they are perfect, and the rest of trainers behave as usual.

Has anyone ever experienced this before? Any ideas to fix it? Thank you very much.

PS: I'll upload a picture later
