When you add measure points such that the area enclosed by the route along the points is not convex, then the area is not calculated (or displayed) correctly. It seems that there are "negative" areas, but the little info box does only show unsigned values of roughly 255 million km².

Steps to reproduce:
Place three measure points like in "N" oder "Z".
(It works for any odd number of points on a zig-zag-line as well.)

Easy solution: allow negative values and let the user know that 255 million is actually a miscalculation

Best regards,
