Multi-slide video Resume on first slide

Hi All, I’m creating a course with a video using a multi-slide option and divided the video up into 5 slides.  I want the scorm to bookmark when the user exit the course and resume on the last slide they were on.  However, when the user resume the video always starts on the first slide.  I’m using Captivate 2017 now and it’s not working how it did on captivate 9.  Can anyone suggest a solution?
