Under the reports tab, when you click on Filter beneath the concerned report, you would only see the dropdown and dependent dropdown fields. Fields such as Single line texts, Check-boxes, etc. are not included.

For a data dump of all the fields, please navigate to the Tickets tab -> and do an export (highlighted in blue) from the right side of the tickets list view.
