Cannot define area

Description of problem I try to define a narrow area, which encloses only > 2000m elevation. It looks right on full screen, but when I go from map view back to saving, it has one of the coordinates at -351.66 and refuses to save tha area. It worked for many other similar areas in the Swiss alps, but not for this one. Why is that?

Worked for Flüelapass CH, Albulapass CH, Julierpass CH, Berninapass CH etc.
Doesn’t work for Grimselpass CH

Thanks for helping! Happy New Year!
