Upon making a map for my world, everything seemed to be working fine at first. I made the map, set the image, and began putting up markers. Then, upon editing one of my markers, changing its colour from black to green, the entire map stopped displaying itself in the editor. All my markers were in 'Markers' section, but the image itself, and the markers were gone. On top of this, when I tried to view the map 'in world', the map would appear but none of the markers would show up.

I've already ensured that each marker has been set into a marker group, and toggled the box that displays the markers when loading initially. I've also switched to a different browser, restarted my device, logged out and back into of my account, and even tried remaking the map entirely, but none of it fixed my issue (remaking the map resulted in the exact same thing happening. It was honestly really crushing to lose all that work twice in a row. What can I do?
