Excessive Waypoints

[tommyback]

Hi, Just started using OM. From openandromaps I downloaded and added the Colombia map that I will use two weeks from now. I have finished making Wayponts for my route, about 3000 km. It worked fine until close to the end, adding Wayponts, moving them, editing them. Then, suddenly, I can add more Waypoints, but the green ones suddenly becomes red, even the previously added ones, and they cannot be moved or edited any more.

Please explain. Is there a solution?
