Clipping plane not filling when saving model to pdf

When I apply a clipping plane it fills, then after a few moments or I navigate to something else the fill disappears. Panning makes it come back. When I print to save as pdf the fill doesn’t show in the preview either or in the pdf I save. If it helps at all the images look different in vector and rester. The lines are very thin in rester but thicker in vector. I was using clipping plane and saving with no issues earlier today so this is pretty frustrating.
Thanks, Tevita

Hi Tevita -

Hi - please run the Rhino SystemInfo command and copy-paste the result here.
