Creo 9 Modelcheck Drawing_name and First_model

[HW_9564609]

I'm testing out Creo 9.0.4.0 and have ran into a problem with validating the drawing_name matches the first_model attached to the drawing. 

DRW_MODEL_NAME EQ FIRST_MODEL had functioned just fine in Creo 4 for us. The strange thing is the check still seems to work, but on every model check an error of FIRST_MODEL is not a legal function is thrown. If the names mismatch it ALSO lists that they don't match.

Anyone seen anything like this?

Note I've tried this with both the old UI and new. The screenshots reflect the old_UI

I would open a ticket with PTC. DRW_MODEL_NAME EQ FIRST_MODEL should be valid per the Creo 9.0 help documentation on ModelCheck Model Name.
