I am also having this exact issue. I am running a multisite thru Cloudways, and we don't have access to the OCP settings at all since it's a drop-in. They disabled it and my MB Relationship data was on the front end, but not having OCP is not really a solution. Is there anyone who has a fix for this? Is this something that will be patched in a subsequent update from Metabox? Bricks? OCP? I'm not even sure who to submit this to, so I intend to post on the Bricks forum as well, at least
