Relic Castle

I was adding trainers (specifically Gym Leaders) and after I got done adding them in the trainers.txt file (I am doing a continuation of Red and Blue so the leaders were already defined) and booted up my game this came up

It's saying that LEADER_Misty should be a Pokemon and not the trainer, I don't know why it expects this. This is what my .txt file looks like
The Team Rocket member is the same one that came with the .txt file when you first get Essentials all that I did was edit the her team.
Thanks for the help and look out for my game Pokemon Prime coming this week (hopefully)
