When I export a volume as .shp from the software:  
  
I get these outputs:&nbsp;

When I try to import a volume I see:&nbsp;

If I select the vertices only, I get this error message:&nbsp;  
Selecting the surface object solves this issue.&nbsp;

I would suggest to compare the shapefile you have created with the one you can export from the volumes tool, to see if they have the same format.&nbsp;

Let us know how this went!
