I checked, and this doesn't happen here, it seems you have conflicting scenery, and it's likey the Asobo KORD.
The most telling picture is the one with the jetblasts close to the PP PP1> sign, see the attached screenshot how it normally looks like. In yours, in addition to the terrain warping, you have two set of jetblasts, one of them not belonging to our scenery.
The Asobo KORD (or any other default scenery) is not exactly intuitive to remove: if you remove the package manually, it will be downloaded again automatically on the next start, the only way to remove it and not having come back again, is to remove it from the Content Manager, then restart the sim.
