Non-Plot Layers No Longer Visible in Paper Space
Issue
Your non-plot layers are no longer visible in Paper Space.
Solution
You need to tell AutoCAD to make your non-plot layers visible. You can do so by using the AutoCAD Page Setup Manager. Open the Page Setup Manager:

File menu, Page Setup option
or type PAGESETUP in the Command line
The Page Setup Manager dialog box will open. Click Modify.

The Page Setup dialog box will open. Check the Display plot styles box beneath the Plot style table menu, near the top right corner of the dialog box.

Your non-plot layers should now be visible in Paper Space.
