Category-Products Redirects problem

[Forgo]

Hi,

i have this category tree in ps 1.7.2.2 with friendly urls enabled

1 - man (https://my-site.com/3-man)
1a - man-t-shirt
1b - man polo
...
2 - woman (https://my-site.com/13-woman)
2a - woman-t-shirt
2b - woman polo
...
3 - children (https://my-site.com/26-children)
3a - children-t-shirt
3b - children-polo
...

Each sub category has more than 1 product.
If i go on any category page or product page it works, but all the woman category pages (products associated with this category and sub-category pages) redirects to https://my-site.com/t-shirt-man/1-259-t-shirt-premium-man.html (a man t-shirt product (id 1)) and this makes  no sense...

In the debug console i see a 302 moved status when i target any woman category/product and then it goes with the redirect.

Thank you
