I have an unwanted icon on all my writer docs and I cannot remove it

There is an unwanted icon in the top left corner of all my writer docs. I am not able to get rid of it.

Does it appear in page preview and in print?

What shape is the icon? Is it an anchor in the top left corner? Do you have any image defined in the document template? What operating system, version of LibO etc. Have you defined your own template. Have you imported some other type of document such as .doc or .docx?

Could you possibly show a screen shot?
