I'm on 1.12.2 minecraft, mod version 4.6.3, and I wanted to make some pretty maps downloaded, but when I did, all that came up was the markers, not the biome indicators themselves. Is this an issue with my install, or a mod issue?

The same problem. A blank card is saved. I tried to put markers, yes, there are markers, but nothing else. I have it on version 1.16.5
