In my Grasshopper file I want to load a profile family, but by every change in the GH file an error occurs in Revit saying that a parameter of one type is not filled in well. However, actually the parameter in question is filled in like it should, and I can still make elements with it in Revit.
I tried deleting this type and deleting the whole family and reloading it again, but the error remains.
I hope someone can help me out! 
The component in Grasshopper
The error in revit
The parameters of the type
