Added unnecessary loading stop after extending the route

With this route, which runs according to my wishes:

https://abetterrouteplanner.com/?plan_uuid=6eec07dd-9acc-4d86-ade0-e5670d1f048d

If I add any other waypoint after the last stop (a charging station), an additional charging stop is inserted in the middle of the route for unknown reasons, which was not necessary before and is not necessary afterwards either.

E.g.: https://abetterrouteplanner.com/?plan_uuid=cdcab373-ce87-462a-88a5-110f12c60c23

I am despairing. I have no choice but to plan and save the rest of the route separately
