Welcome to OpenStreetMap and thank you for contributing! Please use the changeset description field to describe what you changed and why—for example, "Added airport features by tracing aerial imagery." You can find more examples here: https://wiki.openstreetmap.org/wiki/Good_changeset_comments Also, try to save your changes in one area before moving on to another, to make it easier to see what changed. Finally, I see that the runway 14/32 with way ID 22697657 was already tagged with "abandoned:aeroway=runway," which means that it's a runway that is no longer in use. Adding back the "aeroway=runway" tag implies it is still in use, so if it is, the "abandoned:aeroway" tag should be removed. If it is still unused, the "aeroway" tag should be removed.
