Unable to remove watermark when editing files in Collabora

When editing office files in Collabora there is always a watermark visible, showing ‘seafile@mydomain’ and my user name.

I explicitly disabled watermarking in seahub_settings.py by setting ENABLE_WATERMARK = False.

Nevertheless i still get the watermark. It’s added to the HTML file containing the editor, but outside of the iframe containing Collabora. Disabling the node removes the watermark:

I’m pretty sure that it’s added by Seafile, despite the settings in seahub_settings.py. Is there a way to get rid of it permanently?

My Seafile Version is 8.0.5.

Have you customized the code yourself ?

I didn’t customize any code, I used the Developer Tools of Firefox (Firefox → F12 or CTRL + SHIFT + I) to view and modify the live view. The screenshot was taken of the code view of the Developer Tools.

We will check the problem.
