How to edit Part SIP-1A05 Reed Relay?

Hello communuity,
just working on my first project which uses a SIP reed relay and was happy to find SIP-1A05 REED RELAY.fzpz on the net.
This is exactly the part I am using and the picture shows the correct housing with 4 connectors, however in the schematic (and PCB) view the part has 7 connectors.

By trying I have not found a way to remove connenctors 5 - 7 and therefore I would like to ask for a short hint on how to get rid of these pins (or perhaps a link to a ‘correct’ .fzpz ?).
Be assured, your help is deeply appreciated,
thanks a lot,

These two tutorials on parts creation may help

I lately learned there aren’t links to the videos in Old_Grey’s tutorial so you need to do a google search for the title and then they come up on YouTube.
