Why do ERP roles have duplicate data security policies?

Summary:

I have seen in multiple different ERP roles duplicate 'data security policies'. Is there a reason there are 2, 3, sometimes 4, of the same policies? I have checked and they are exactly the same, just duplicated. Can I remove the duplicates? I have an example screenshot below of the 'Application Implementation Consultant' role with 2 of the same exact data security policies.
