GZ red/green markers in Descent and ErcanaCitySilo show as clickable

[ZarothYe]

The markers in Descent and Er'cana City Silo show up in-world as clickable (like they were in TPotS/CC/offline). When clicked, they make the "marker collection" noise, but don't disappear or add themselves to the KI. The red marker button in the KI must still be used to collect them properly. Seems a bit confusing and we should probably remove these click regions/hotspots/whatever so they are consistent with all the other markers in the red/green collection quest.
