Hello. I am working on a StoryMap for a project at school about climate change, and I am having some problems putting maps on my StoryMap. Sometimes, certain maps show up on my StoryMap, but sometimes when I go and work on it again, they just show up as a dark, blank rectangle where the map should be. Sometimes this only happens with specific maps, while sometimes this happens with almost all my maps. It usually happens with some maps that I made using a csv excel sheet:

But it it also happens with maps that have data layers I found on Living Atlas or ArcGIS Online.
This is a really big problem for me because now I can't insert maps, make map actions, or just see how my StoryMap is looking. When a map doesn't show up and I try to delete it and insert it again, this happens:

I can't see the map and the "Place Map" button won't work.
I tried publishing some maps that I want to put on my StoryMap and then tried inserting them again, but that still didn't work. Does anyone have any advice for me? I would really appreciate it. Thank you very much!
