Planning a tour in Spain, I tried to add a waypoint beyond the end of an existing route.

The new waypoint is at Trujillo but, by mistake, I selected the Trujillo in Honduras rather than the one in Spain.

I got the message "Can't plan a route across the sea".

Fair enough.

But then I tried again, this time selecting the Trujillo in Spain.

I still got the "Can't plan a route across the sea" error message.

I can't work out how to clear it.

Help!

The route, for interest, is https://cycle.travel/map/journey/945912
