When using a "Collection" landmark (Where you collect items from) there is an error with their default approach distance before interacting. If you try to use the landmarks while under 100m but above 10m you get an error and your robot makes no attempt to move lose.

This does not happen with "Submit" landmarks as your robot will try to move to 10m away before accessing the landmark.

Looks like a typo in the distance perhaps? Ticket Raised. #388 - Interactive Landmark
