See earlier post on May 31, 2018 with same question from same poster. This thread is locked.
As you get the grey boxes in PDF, please check the if the "Show Large Images" is selected in the application preferences.
To check that, launch the application and go to Edit > Preferences > Page Display.
Under the headline, "Page content and Information", make sure that box for "Show Large Images" is checked.
Click OK at the bottom to save the changes in the Preference window.
Check if that resolves the issue.
If the issue still persists, let us know if this is an issue with a particular PDF or with all?
