Activity/Slide not displaying

Installed Opigno 2, via composer, using Acquia DevDesktop 2.0. Added a training, and was having issues with Slides displaying. http://web.dd:8083/admin/structure/opigno_activity_type/opigno_slide/ed… On the Display settings, Default & Activity: the content field is not displayed. is this a bug or a slide on Opigno 2.0 are only PDF? Spent two days on this... :-D I thought it was my install that was incorrect...
