Drawings in Layer Visibility

Hi, I’m using Harmony 16.0 Premium and I’m having a wierd problem, the drawings of one specific drawing layer disappear when I click on it, but when I click on a different layer the drawings on that layer will reappear. Help?

Check the advanced layer options. The drawing may have been
done in the underlay or underlay layer which may not be selected
for viewing.

If you’re stuck, please contact support to have a look.
