PDF Footer Line still appearing despite changing footer style sheet.

Hi all

I have a custom footer on each page of my report that is an image. The image is appearing correctly and I am happy with it. However, the default footer (a black line and a page number in the bottom right corner) is still appearing in the same space.

To replace the footer, I changed the "Footer Content" entry in the stylesheet, and saved it as a new stylesheet. I can't find anything in the style that logically causes any footer OTHER than my intended image to appear. Has anybody experienced this issue?
