There is an invalid signature error #256

Hello, I'm trying to validate the XML, from the EFD Reinf, from the Federal Revenue of Brazil, but I'm told that the signature is invalid.
I already use this library in other XML signatures and it signs normally, but in this specific case I am not succeeding, follow the XML and the code PHP.:

I need to sign the XML in the tag that is inside Reinf, the signature must be inside the Reinf tag:
