Nintex Workflow Cloud -Create a SQL Record - on prem -not populating fields on one table.

When using the create a sql record for Microsoft SQL Server On-Premises one of my tables will not populate the “Add Fields” field. It sees the table and all of the other tables using the Nintex Gateway. For some reason this particular table does not retrieve the columns. Scratching my head as perms are the same, everything is the same.
