Prestashop 1.7.8.8 why Home is aways checked when i add new product?

[Essemme_Forniture]

Hello Guys,

i've just installed the ps 1.7.8.8 and i was trying to add a new product.

When i was using 1.6, i was used to go to the category, example , "home 3" and add product, that product Automatically went to "home 3"

With 1.7.8.8 if i go to category "home 3" and i add the new product, ( if i don't change the position) the product will be always in "home"

in a nutshell it doesn't go by default in the category where I chose to add a product

Do you know why?
Thanks for support
