I assume you expect that link to go to the switch at the other end of the port?
It does not as Observium has not identified them as neighbours, you only see some of the LLDP-information.
You need to make sure both switches run LLDP, have configured hostname and domain-name that matches your DNS-record.

I don't understand the question.

What isn't working? What do you expect to happen?
