Asset Classes in t-code OX10: missing in AS02

Hello Gurus-

A puzzle. When I review the configuration of the asset classes in t-code OX10, I see a listing of asset classes by field groups. When I view the asset classes by transaction code AS03, there are more asset classes not found under t-code OX10. Why is that?

Do they need to be configured? Is it missing configuration?

Shouldn't I see all Asset Classes via OX10?
