Making changes to the slide’s name and description in Map Tour story map with HTML and clicking around while the wheel is spinning lead to other slides to inherit names and descriptions automatically.
Closing this out as non reproducible, as could not reproduce the issue in the session with user. In the tour, the images seem to be individually added into ArcGIS Online at items and then added to the tour via URLs, which may be a factor in what was saw before. Showed the user that is not efficient or recommended workflow for adding images to story maps, especially ones with multiple images like Map Tour.
