Missing Parameter Group Type "Other"?

Trying out my first Dynamo implementation, to create Project Parameters from an Excel file.

Figured out how to access SpecTypes and GroupTypes as strings, to pass to the Create Parameters, but in doing so, I’ve noticed one of the Group Types appears to be missing?

“Other” is available in Revit, but is missing from the picklist, to find what the correct string is:

Is there another way to find out what the string for it would be?
