Anyone have an issues with Phoenix Mountain collection chest?

As the title says. I can't open the first collection chest as it is already open.

Anyone else have this issue?

The only issue I encountered that symptom was after I collected everything collectible (still have 2 quest rewards to go).

The next collection chest I found afterward opened, provided nothing, and stopped being Revelio'd or interactive, but the icon stayed on the minimap. Since it was in an instance off-map and I had everything already, I don't really care about the icon.

I've never encountered any collection chest opened before I opened it. I have collected chests prior to receiving the quest that leads me to the instanced location (though usually blocked from progressing further into the instance by some quest-related obstacle). Those chests worked normally and weren't identified as collection chests the second time I encountered them inside the instance while actually on the quest-no Revelio, no icon, no interaction.
