Weird vertical lines w/ Optima

Last week while saving, my project developed strange vertical lines on all chapters of the document in which I was using Optima. I’ve checked other projects and they have the lines, too. I tried closing Scrivener and re-opening it but the lines are still there. I can change the font and the lines disappear but that means changing the font on all chapters. Any thoughts? Thanks! And Happy New Year!


Very strange! Could you please post a screenshot? Do the vertical lines appear in TextEdit when using Optima (which may indicate a corrupt font)?

Happy New Year to you too!
All the best,
