I am using the Sway template. I can create gallery content just fine, but if I notice a misspelling or forgotten tag or something that requires me to edit the gallery, as soon as I open it in Joomla everything in the "images and links" and "gallery" tabs gets dropped, so I have to add all the images back to the gallery over again. This will be a recurring problem as I need to update metadata or other items. I set up a demo gallery at the following address:

In the back end, you can see the gallery in the article manager as "Joomlart Demo". If you need to replace images to experiment, they are found under images/joomlart
I feel like this is a joomla issue and maybe there is nothing that can be done about it. However, I am having another problem that I think is a template matter that can maybe be fixed with css. The 2nd problem relates to the captions on the images in the gallery. When the site loads in mobile, the captions are spaced out among the images as they should be, but if I load the page on desktop all of the captions appear at the bottom of the page stacked on top of each other. If you have a suggestion for this I would be very appreciative.
