GPS wrong - running.

Impossible for me to run 2.20/km All the time on the watch I see that the pace shows from 2.20 to ~3.30 !?. What's going on with this GPS? Auto lap after conversion gives the correct pace, e.g. 5.45 / km, but when running, the watch shows something else. I deleted the entire remoteSW directory, but that didn't help. 

Check GPS, GPS GLONAS, GPS GALILEO. Everytime its the same..
