Problems checking grouped values

Good morning, I am creating a report that looks like the following;

My problem is with the "Type" field that is grouped

As you can see, the "Check" field gives me an error, in that field I would like to obtain the same values that are in the "P" column, which, as I said, is a grouped column called "Type"

The idea is to count all the "BaleID" where "Type" is equal to "P", I have tried the following expressions and I get an error, I can't think of how to achieve it.

=Count(Filter(Fields!Type.Value,"P",True, Fields!BaleID.Value))

=Filter(Count(Fields!BaleID.Value),Fields!Type.Value="P",True,CompareMethod.Binary)
