The airport is not part of the navdata delivery from Jeppesen and hence is not shown/selectable in our apps. We have no influence over which airports are included and which are not.
The runway is visually shown in Charts because it shows underlying data from OpenStreetMap, and it seems to be included there. But we take no airport data from OSM, hence it can’t be selected.
Additional to Stephens answer, there is no official record in the Russia AIP (at least I haven’t found any with this airport code in the AIP). This happens normally, when airports haven’t an international status.
When airports aren’t included in the AIP, they are also not included in the standard sources of the data provider because the AIPs of the countries are the data base.
