Single Table inheritance and EM question

First project using EM and single table inheritance, I've got an abstract base entity, with three concrete sub types, I'm putting a qualifier in the Basic Tab's Qualifier field in the form of (summaryRangeType="hour"), etc for each of the three types, obviously with different values for each. The column used for differentiating the types, "summaryRangeType" is a class property. There are some reflexive relationships between the the three sub types, which are always used, but not constrained as mandatory. Fetches to one are resulting in generated sql to all three types, as if I'm fetching on the abstract parent, which I'm not. What am I forgetting or not doing correctly in EM? Thanks.

Bill
