Atlas "Failed map"

I just got to a node in the atlas where there was an Untainted paradise map with beyond. I finished the map killing all the enemies inside with 0 enemies remaining, but the map didn`t show as completed and the nodes close to it didn't open. I opened another map in other region and then, the untainted paradise turned red colour and as "Failed Map", now i cant go through that part of the atlas because is the only way i've found...

The same just happened to me. It was a +400% experience gain only (no items dropping from monsters) Untainted Paradise and after clearing it to 0 monsters and running all around it to see if I missed something it still appeared as "in progress", and after exiting it and then activating another node it became a failed map. I hope this is fixed because it's really unfair to have a failed map when I cleared it successfully.
