SDSiteAdmin role can't select Change Implementer

SDSiteAdmin role can't select Change Implementer

I have a user that is set-up with SDSiteAdmin access under our MSP default site (OSC Host). This person is entering changes into the system for us however they aren't able to select technicians for the "Implementer" role. They can see the list of technicians but can't select anyone. The technicians are all set-up in the same site (OSC Host). Not sure if this is a restriction with the SDSiteAdmin role or if this is a bug? 

Thanks,
Tammy
