Hi dickandanita
I'm not with Laminar Research, just a fellow simmer in the UK :-)
I loaded up a Cessna 172 flight at Atka, Alaska (PAAK) and got the same message. In fact, when you look at the internal X-Plane 11 VFR map (press M key) and zoom into the airport, it shows runways 15 & 33, not 16 & 34 which are actually the correct ones based on the latest Jeppesen charts.
Cleary there is a conflict of information here, so it is advised to report missing or incorrect runway information to the X-Plane Scenery Gateway @ https://gateway.x-plane.com/
Hope this helps
Regards
