Double image while engraving insulated tumblers

Can’t seem to solve my double image engraving on insulated tumblers. I don’t notice the issue while engraving on other materials.

Do you have a roller or a chuck type rotary?

Is it the same problem if you change scan angle to 90 degrees? That will help narrow down the issues. Please post a photo and your lightburn project file so we can look at what you are working with.
