Treasure Maps generate as blank maps instead

When exploring ocean shipwrecks, treasure maps I've found are replaced with empty/blank maps. To clarify, when opening the maps, they do not show a map with an x on it, with a player icon off to the side, it's just a normal map. 10 Ships explored  on my world, made on 12/2/21 on the current version of mc as of the making of this post.
