Strange Errors with blender file in unity 5

Hello :)

I made a model and some animations and saved the blender file to my unity project.

Everything looks fine and I can use the model and the animations, but I am getting spammed in errors and is now causing massive FPS drops.

Here are the errors, (Note, these errors pop up if just click on the object in project browser, they will spam if I use them in a scene, or even if I rotate the model in the project browser preview box)

Thanks for the help :)
