Can't get Campaignee table data via XML-RPC API

I am using the XML-RPC Api to try and get data from the campaignee table using Query a Data Table.
I am not able to get any data back. It works for other tables but not this one. Any ideas?

The tables, Campaign and Campaignee are legacy tables for the campaign system prior to the current campaign builder. There is no access to most campaign information with the current builder although REST does have some details available:!/Campaign/getAllCampaignsUsingGET
