Smart Quotes (again) with asterisks?

Cheers folks. I’m using Markdown for my manuscript, and running into this problem. I use italics for both internal voice and for remote speakers such as those on phones. However, when a smart quote is adjacent to an asterisk (either before or after it) it causes the smart quote to always produce a ‘closing quote’ - so all my lines/paragraphs in italics have incorrect quotes, with ‘right quotes’ at both ends. Has anyone run into this before? And does anyone know how to fix it? Many thanks. Oh, I’m using Scrivener 2.8.0 (26284?) on OS X El Capitan. Thanks!
