Going over cut twice

I have a drawing from Inventor, exported as a .pdf and opened it in Adobe Illustrator. I highlighted it, object>flattened transparency, and pathfinder>outline. I wasn’t able to “trace logo” under quick actions like in the past. When I ran it on the laser it went over everything twice even though the path was set to one.

There are two lines or the Glowforge would not make two passes. Open your file, zoom in and look on outline mode. You will see two lines.
