Updating .smg file

Hello,

I have an .smg file with several views of the assembly exploded in a particular sequence. The views are fine and I would like to keep them, however the original model I used did not have its meta properties filled out, so when I create a BOM no values populate, such as description. I add the meta properties and saved a new .smg file, but when i try to update my original .smg with the new .smg using: file --> update .smg I am left with views that have my 3d polyline (which i used as an exploded line) but no model. What am I doing wrong, and how can I fix this?

Thank you.
