List not displaying correctly in FB IA

I created a post today on WordPress and then posted it on facebook. When I reviewed the post on facebook it was using the instant article, but when it loaded it was not displaying correctly. It should have had a numbered list with sub-bullets. The numbered parts displayed, but the sub-bullets did not. To remedy I unpublished the IA, and am pleased I caught it! However, if there is something I am doing wrong or if it is something that needs updating in the plugin I would appreciate knowing! Thanks you!
