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 and click on the arrow next to each segment you want to delete:
A drop-down menu will appear and select Delete Segment:
Then select DELETE in the pop up window:
Continue this process until only one segment remains. You can then schedule the job to reoccur as you normally would.
