ACF field group not showing in page

i've created an ACF field group just for one page, since my clients will need to upload 2 files directly related to that page (it's a page about a basketball team, so they'll have to upload the leaderboards and upcoming matches from time to time). So i've set up the field group like this:

As you can see this field group only shows if the page is 1° divisione (the team's name).

But when it comes to call that field group in the page, it doesn't show - as you can see from the screen below; instead completely unrelated field groups are shown (these 2 field group are used for posts, not pages).

What am i missing? I need those documents to be file custom fields as i've created a front-end dashboard for my clients to manage the posts, and i want to add the edit files functionality.
