I'll look into these now. Chile is one of my favorite rides and had white dots going the right direction last time I checked.
For Czechia, gates show up to the nearest white dot within 15m, so its end point is probably just outside that range. I can fix and give you credit for the ride!
For South Africa, do the dots reappear if you restart the Explorer app and resume that ride? That usually fixes it on rare occasions the dots don't download, but I'll also to fix automatically with smarter loading logic.
