Cannot enroll different system person types

Hi,

We have different person types in our organization. Let´s call them Regular and Seasonal. Both are defined as system person type Employee. The first one is the default and both are active. In OLM, when I try to enroll a person with Seasonal person type, using the Single  Enrollmnent option, this kind of employees do not show in the find window, only the Regular ones. If I do the same, using the Bulk Enrollment, for the same class, all types of employees are shown.

Is this functionality or a bug?
