Movie layout page control issue

I have found a little bug in the page controls on the movie listings.
When using the page up/down or the on-screen scroll bar the movie tiles jump 1 too many.
On the screen it shows 5 plus a slight bit of number 6 on the right

page down and it jumps to number 7 with number 6 just showing a bit on the left

It should be showing this
