strikethrough becomes underline on export. can't get it to stop

When i try to compile a scrivener document and export it to another format (Word, Open doc, etc.) it turns most of my strike throughs to underline, although it sometimes does leave the first few strikes alone. It’s super annoying. If I do straight export, not through compile, then it leaves things alone. I’ve tried clicking and unclicking lots of things, also changing the engine used for converting, nothing works.
