Easiest way to add restricted parameters to Models?

[BH_12246893]

Creo has neat functionality in the restricted parameter list.  Creo also has nice functionality in that you can import an .xml file to add parameters to a Model.  It would appear that these two do not play well together.

I am trying to update legacy models that have missing parameters and my .xml import was working wonderfully until I updated my restricted parameter.lst file.  

I get this message:  

Is there any way to make the import work?  Is it a matter of my restrictions in my .lst not EXACTLY matching what I have in the .xml?
