menu parameters basic

Hi

I have setup the Parameters Basic for my menu item like these (the same of the screenshot)
#leading 0
#intro 10
#colums 2
#links 0

but into the page the result is:
#leading 01
#intro 4
#colums 2
#links 4
(the same of the default for Parameters Basic)

the website
www.elementiarchitettoniciantichi.it

I have tried to re-saved the parameters, making a new menu but without success.

thanks in advance for your help,
Daniele
