Problem with update spec in 3D model

[mcray100500]

I have changed some property values of components in spec. Than I make update spec in model and program displays items that have been changed, but I can not click on the checkbox "update details". I think, it may be due to the "not found in spec" in "Spec" column.
I don't understand, why is it happens. I use only one spec and all details from this spec.
Please help me sort out this issue. Screen is attached.

Thanks in advance!

We are having exactly the same problem here. The customer wants to have the BOM descriptions differ from our usual long family descriptions so we have edited the catalog and spec to suit, but these changes are not following through into the model.
