ERD - Object Relational Mapping - Reverse Database indexes not being mapped

I am trying to create an ERD from an existing SQL Server database. I am using Object Relational mapping/Reverse Database. I am selecting a subset of tables from my database. The tables are retrieved correctly, but none of the indexes from the tables are included. When I opened the specification for a given table, I expected all of the indexes to be there. None were there. I am new to Visual Paradigm so am I doing something wrong?
