Blockbench changed model type but texture isn't working

I made a model on Blockbench of a Guardian in BotW to use for a mod as an entity. But when I tried to export it, I realized it was a generic model, not a Modded Entity model type, which won't work. I converted it using File > Convert Model and made it a Modded Entity, but then the texture didn't copy over. It looks like the UV overlay isn't the same so it won't match up with the texture I made anymore, so it looks really off... Nothing matches up and as an example parts of the leg textures are on the face. I don't want to have to retexture the whole thing, so is there a way to change the UV overlay?

I have the original one as Generic and the Entity one saved right now. In case those are needed. 

Picture of both models!
