The site talks about "telephone data" yet the picture example (https://www.everyoneapi.com/static/img/bruce.png) has a status (presume relationship) of "single", what else are they using apart from "telephone data"?
When I'm watching at their example, the only 'status' field has a value of 'true'. I don't think it's about relationship, more likely about the phone-line being active.
