For instance, at random, I have just open the WildSide website template and the "Made with Xara" there is in a Repeating Group on the MouseOff layer.
To remove such, go the Page & Layer gallery, open a page in the Layer view and ensure the MouseOff layer is visible.
Go to the Footer.
With the Select tool, click on the text and then press the delete key.
A pop-up should open and you should click the Delete from all pages button.
