I have heard of this with respect to Flightbeam’s KDEN, however I have not seen any threads on this with respect to default scenery. If your KDEN is uninstalled, I wonder if you were to clear your rolling cache of you would still have that issue.
(By the way, I removed the tag #scenery. Airports have scenery in them, but generally, we use the #scenery tag for scenery packs like cities, landmarks, etc.)
