You know how to create recurring visits, but on this particular job the option is not available. A recurring visit cannot be setup on a job that has multiple segments.
To delete the additional segments go to the job details page of the job you would like to delete. Click the wrench icon toward the top right of the page.
A pop-up menu will appear, click on the first segment that you would like to delete.
Another menu will appear. Click 'Delete Segment #X' to remove that segment.
A confirmation window will appear to confirm the action. Select 'delete' in the bottom right.
Continue this process until only one segment remains. You can then schedule the job to reoccur as you normally would.
