'Type Mark' parameter missing in door family

[skyeg321]

I have this door family and the parameter 'Type Mark' is missing. I thought this was a built-in door parameter that could not be deleted? Does anyone know where it could have gone?

It doesn't show in the family editor, only in project.

Type Mark is a system parameter that only shows in projects.

Instead of type mark, I would use Model as your parameter. That way it is easier for you to load the model type into the project.

For type parameters I like to use a fixed value (and not something I set for each project). I created a shared type parameter. Your schedules and tags also need to use that shared parameter. That is the only way if you want to set it in the family for all future use.
