To add your own logo, first delete the old logo from all project pages. Press the “Delete” button and select “Delete from all pages”. Then drag the new logo to the document. Set the logo in the right place. Enable repeating the object on all pages by right-clicking on it and selecting from themenu “Repeating object, Repeat on all pages“. Check if the logo appeared on other pages. In my example, I will also set the color of the logo on one of the Theme Colors.
