Modality changing study instance UID of my worklist

[Weslley Dutra]

Hello everybody!
I am generating my HL7 file and it is being sent successfully. And in my modality it also receives success. When finishing and submitting the job, dcm4che creates a new patient with a new study instance UID. Any idea if something is wrong?

My hl7 generate:

Check if the modality is configured to map the PID Issuer and Study UID from the MWL into the dicom files it creates.
