Not able to checkin a drawing after format update form windchill

[AK_10613585]

I am using Creo Parametric Release 7.0 and Datecode7.0.9.0

Not able to checkin the file

Here are the errors that I faced
The value of "Type Definition Reference" cannot be set to null, since it is a "required" attribute.

The error itself is saying that whatever you're trying to check in doesn't have "type" set as an attribute (likely CAD Drawing, CAD Part, CAD Assembly, etc. is unresolved). 

Is the drawing the only thing that's being checked in (I'm assuming that would have a type defined) and there's something else that's coming along for the ride that's not? Like a ghost-file or something like that?

On the check-in screen what all is getting checked in when your table view is "set for check in"?

Everything looks fine, this got resolved after deleting the models and views, adding them back in
