It's really easy to remove the table of contents from a report or permanently remove the table of contents from all reports created by you (and your users).

1) Remove the table of contents from a report

To remove the table of contents from a report simply uncheck the corresponding tick in the Include column within the Report Builder.

2) Remove the table of contents from all reports

If you'd prefer that the table of contents section wasn't included and didn't show in the Report Builder of any reports created by you (or your users), this can be achieved by hiding the section via the Report Section Manager.

If the plan you are signed up doesn't provide access to the Report Section Manager and you haven't purchased it as a bolt-on to your subscription, you can still stop the content of the table of contents coming out in your reports via the Report Content Manager. However, the table of contents section will continue to show in the Report Builder.
