Thank you Kat05, updating to 2.5.7 did the trick. But another issue I noticed is that when I clicked on each if the pages that i wanted to apply the new layout to, the check box would disappear. That i can live with.
Many thanks,
Houston
hi houston,
glad the update helped! 
if you still have issues with those checkboxes, feel free to send me your details and an example of where they wont work via pm.
thanks, kat
