Diabolik Theme Shows Through New Skin

Hello, I have installed Diabolik theme and then modified it to our liking, however on our
photo gallery page, when scrolling down the page to view other galleries the Diabolik theme template shows even if our config have been made.
This link will bring you to a gallery page where when you scroll down the problem which I stated above can be viewed. https://qnr.ca/media-gallery/photos/car-meets/st-eustache-drag/
Please if anyone knows this issue can you guide me in the right method of fixing this..
Thank you
