Video Slider Not Looping

Hello;
I’ve created a series of slides each with video (5 so far), but I can’t get the slider to successfully play the first video when looping back to the first slide and starting over. I get the first frame of the first video and then it freezes as a background image. When moving onto other slides, the type changes, but the first video’s frame remains stuck and no other video content plays. Is this a common issue?

Thank you!
