I have several relationships between CPT's. I had em set to reciprocal. But that wasn't necesarry so removed it and also changed the order on the 'from to' on some relationships to have em all the same.
But now on some relationships I don't have the correct couplings showing up? Is that a caching issues?
Can I reset it without losing the relationships? Is it caused by where I originally set the relationship?
There is no caching for relationships set up on the backend. Can you please share some screenshots before/after changing the order?
You can also access your database, open the table wp_mb_relationships to see the order of the post (object). Read more on this documentation https://docs.metabox.io/extensions/mb-relationships/#database
