In the current design of data source import rules, when we create one source for two different rules with different types of data to be imported from the same source and have the delete checkbox enabled, a mismatch of import data is performed.

Scenario:
A code review shows this was an intentional design made a long time ago.
The best practice is to have one data source created in the ITMS console per each rule created in the console.
