Objects showing up on a slide from another slide
I'm working on a project where the user clicks on a button and it takes them to another slide to watch a video. They can then return to the original slide, click another button, and view another video. There are three videos. When the user returns to the original slide the first time, it works fine. When the user clicks a second time and then returns to the original slide, the Slide video shows up in the background of the original slide. Why would an object from a completely different slide show up in the background of another slide? And why does it happen after the user clicks a second time? I'm attaching screenshots. #1 is the original slide and the arrows are where the user clicks to jump to the slides with the videos. #2 is the slide visited with the video. #3 is the original slide that shows the video in the background.
