Use the Localisation tab to change the wording in the Trackers. Each site collection has its own localisation settings for each Tracker Type, and each page/document Tracker can be configured separately from the Info panel.

Toggling an option on will allow updates to the default value. Toggling off will restore default value.

Make sure any changes are Saved at the bottom of the page.

To add a back option to the tracker, include the following code snippet.

<span class="ms-Button-label label-250"><a style="Color: White; font-weight: 600; text-decoration-line: none;" href="javascript:history.back();setTimeout(() => { window.location.reload(); }, 100);">Return to previous page</a></span>
