Map inaccessible after placing waystone on node and going back into completed map portal

I have multiple areas in my map that are connected to a completed map node but can not place a waystone in them. Today I found why that is happening by my own hand.

Step 1 - Complete a map node
Step 2 - Place waystone on target map node without hitting traverse button
Step 3 - Enter complete map portal (from step 1)
Step 4 - Find target map node from step 2 un-selectable

In fear of failing a map I go back in to one I just completed to make sure it is in fact completed before going into a new map. I realized that I had some maps that I couldnt select despite a connected node being completed and now I know how I was making this happen. Hopefully there is a way to fix this by just having all nodes connected to a completed map be interact-able and display waystones previously placed in them when they were not traversed.
