Elevation correction using SRTM V4

Imorting a track and trying to correct the elevation of this track using the new SRTM V4 option I get elevation I didn't know giving them in the middle of Germany
Correcting the elevation I have at first to answer, whether I want to overwrite the data ("yes") and then I have to answer, whether I want to correct or to replace the data.
If I choose "no" (so that has to be the option for replace), I get elevations of 3000m near Bonn....
