Why are there multiple arrows connecting pages on my survey map?

The  Survey map shows the default path through a survey and any routing pathways that you’ve added. So, if you have a question on page 2 that routes to page 3, and the default destination for page 2 is also page 3, the map will show two arrows between pages 2 and 3. This isn’t a problem, but you can tidy it up by removing any unnecessary question routing that is already accounted for by the default path.
