Atlas taking player to the incorrect map

I am in the endgame, and I am frequently having an issue where I slot a waystone into a specific map node and it opens portals to a random nearby node. The map nodes affected by this are unable to be entered and completed (as far as I can tell) and can block pathways on the atlas.

For example, I just had a 6-mod Augury map that I put a waystone into. When I opened the map, the game instead opened portals to a Blooming Field map that was located nearby on my atlas with only 2 mods.
