photoshop CC 2019 is not showing source of clone when repositioning over area to be cloned
Historically, when choosing a source to clone using the clone stamp tool (option click), a ghost image of that source follows me to the destination point I wish to retouch. This is especially helpful when I need to line up horizontal or vertical lines. Suddenly, I can no longer see the ghost image of the source. I've restarted my computer as well as Photoshop but I'm still experiencing the problem.
I am running Photoshop CC 20.0.3 on MacBook Pro OS High Sierra 10.13.6
