I have four StoryMaps in a collection. When scrolling through each story map, when the user gets to a certain spot in three of the story maps, they are automatically transitioned back to the collection page. In two of the story maps, the transition happens in the middle of or at the end of a sidecar. In the third, it's right before a sidecar. The transition does not happen every time, although when it does happen, it's always in the same place. If a user leaves the story map open for more than a couple of minutes, it transitions back to the collection page. I don't know what might be causing this glitch in the navigation. Is there something with the way it is set up that might cause this to happen? Someone else created them, but I can't see anything that would cause a problem.
2, 3 and 4 are the ones with the issues:
