We are also having the same issues! Has there been any updates?
I also found this error using Query Monitor: SELECT wp_posts.ID
FROM wp_posts
INNER JOIN wp_mb_relationships AS mbr
ON (mbr.to = wp_posts.ID
AND mbr.type = 'faqs-services'
AND mbr.from IN (9196))
WHERE 1=1
AND ((wp_posts.post_type = 'services'
AND (wp_posts.post_status = 'publish'
OR wp_posts.post_status = 'acf-disabled'
OR wp_posts.post_status = 'future'
OR wp_posts.post_status = 'draft'
OR wp_posts.post_status = 'pending'
OR wp_posts.post_status = 'private')))
GROUP BY mbr_faqs-services_from, wp_posts.ID
ORDER BY mbr.order_from
WP_Query->get_posts()
Plugin: meta-box-aio Unknown column 'mbr_faqs-services_from' in 'group statement' 1054
All of our Relationship Settings are correct and were working just fine.
If I go into each post, there is a relationship field selected but it does not show in the admin columns or the front end.
