Relationship subpanel not appearing both directions

Hello all,
New SuiteCRM user, with strong techy skills including developer.
Go into Studio>Contacts>Relationships. I will use Calls, but could be for any relationship.
Notice that it is many-to-many. I can go to Studio>Calls>Relationships and see the same relationship. Fantastic!
Open Calls. Pick one and scroll down. Note there is a subpanel for Contacts. Great!
Now, open a Contact. Scroll down and I do NOT see a subpanel for Calls?!?!
How do I get the ‘other direction’ to show up?
Thanks!

You may need to do a quick repair only. It happens many time relationship does not show other side.
