Filters Not Working in Preview?

I have Smartsuite connect as my data source. I’m trying to filter a list by a “linked record” in Smartsuite. The filter doesn’t give me any options so I create a custom one.

It works fine while I’m in building mode but as soon as I go to “Preview” it gives me an error saying “No permission to view data in mapped table”.

Anyone have suggestions?

Is this because it cannot see the “linked”?
