19c patch time group missing from repository view

When run the below query

SELECT distinct b.property_value

FROM mgmt$target a JOIN mgmt$target_properties b

ON a.target_name = b.target_name

AND a.type_qualifier3 = 'DB'

AND b.property_name = 'DBVersion'

I receive a return of values as such:

12.1.0.2.190416

12.2.0.1.191015

19.8.0.0.0
