Limited Columns displaying from linked sheet in a Report

edited 01/06/23 in Smartsheet Basics

I'm trying to create a report that can tell me which resources are working on active tasks in my Request Tracker. Some of the tasks are inactive tasks while others are actively being worked by resources.

When I create a form to pull this information and link to the Request Tracker sheet, I only see about 6 of my fields as options of columns to display.

Is it possible I have too many fields in my request tracker and Smartsheet can allow me more than the 6 options?

If it helps, I have about 20 fields in my tracker.
