OLAP parent-child on Power BI Filter

Hi,

On a cube i have a parent-child dimension that work correctly (at least in excel)

Before last week it works correctly on Power BI too ... but from Friday
only on power bi filter works only at level 03 of parent-child dimension, at level 02 nothing filter is applyed

I don't know why
