Word Press new page does always go fluid....

Hi,

I've designed a WordPress template and as layout I've selected 'Fluid' for the 'Home Page' and 'Wide' for the 'Page'. I loaded the template on WordPress but every time I create a new page its content go Fluid (filling the full width of the screen). In order to get page layout to 'wide', I have to open Themler from within WordPress, go under Page, here I find the layout set as 'Fluid' (which should be set as 'Wide'), and change it back to 'Wide'. I save the template but the problem keeps repeating itself every time I create a new page.

Two questions....
1. Why when I upload the template on WordPress the page layout switches from 'Wide' to 'fluid'?
2 . Why even if I change the Page layout back to 'wide' using Themler from within WordPress, it corrects only the single page but every time I create a new one it goes back to 'Fluid'?

Thanks
Sam
