The same query and two différent results on two sites

I copied the query from my first site to a new one.

The taxonomy is hierarchical and I added as parent “{term_id}” as I did before.

In the first site the result was right: see Espagne - Ombres et Lumières

But here, I have a mix of all the terms and I just want the ones children of the {term_id}

I really don’t know what happens
