New Sightseeing Log

Forgive me if this has already been posted or if this is supposed to be posted somewhere else. But in regards to some of the new vistas, it won't let me dismount on certain vistas which prevents me from completing the log, is this an issue? Is there a work around? Help is appreciated.

For some of the locations, you need to dismount somewhere else and find a way to get to the vista on foot. I can think of one in CWH and one in Azys Lla that are like this.
