Data import failed for TB Tracker

Hi,
We are currently using DHIS2 v2.35.2, trying to import the metadata to our training instance (vannila) on exact same version. The dry run completes successfully BUT as you import the data, it gives this error at the end:
Process failed: org.hibernate.exception.ConstraintViolationException: could not execute statement|PCS1qPUqIkZ|*
