Map service, data tab, shows Feature Layers, but not Tables

When viewing the JSON for a Map Service, I switched to the Data tab - My Map service has one feature layer and one table. The feature layer's JSON showed up in the data tab, but the associated lookup table was missing.

This is the rest page for the map service to show how it is configured:

And this is the start of the JSON in the Beta ArcGIS Assistant:

I have scrolled all the way to the end, and the table is never referenced.
