I have an Access 2016 DB with a report that contains several Olebound Objects.
You are saying that the objects are stored in a table field? Reports don't contain the objects, they can only display them. You could post a db (zipped) with enough to reproduce the issue so that others with 2016 or higher can test. I for one question the # characters in your expression if they're really there.
The more we hear silence, the more we begin to think about our value in this universe.
