Click on Add Objects to open the "Add Objects window"
In the top-right corner, you can see the "Connection" drop-down menu. You can click on that menu to choose the QVW NPrinting should import the object from. You can choose both of them, but by default NPrinting is showing only the objects from the first QVW.
Make sure that all sheets and objects are visible in the QVW.
Once you made them visible:
- Generate the object list again (open the NPrinting project, click on Sources, open the connection(s) and click on Refresh Object List).
- Try to add the objects into the template again.
- Now you can hide sheets/objects again in the QVW.
Let me know if it works.
