Unable to dispense medication from non-privileged account

In a patient screen, under the prescriptions tab, going to dispense – it only appears to work for Clinicians under the 2.1.1 upgrade. Our normal process is for Staff (not having the "Clinician" group assigned) to dispense refills.

To reproduce:
1. Login as a non-Clinician
2. Ensure a prescription is available for a patient, and go to the prescriptions screen in their record.
3. Click "Dispense" and fill out fields, enter a Clinician

• It fails, giving the message: "Failed to validate Clinician of Act Clinician: value is required"

Note: If this is performed as a clinician, it goes through fine. As a work-around, we made the nurse accounts Clinicians, but it then lists them as Doctors on other reports/forms.
