OMPC v2.0 adding Active Directory group names over 20 characters? (not allowed)

I've been using Dell OpenManage Power Center for a few months. We upgraded from v1.2 to v2.0.

We've recently gone in to EDIT the Active Directory USER GROUPS under:

       Settings > User Groups and Account > Windows Domain Group

Have noticed the GROUP NAME is limited to only 20 characters. In Active Directory our names are longer than that eg. 'IT - Systems Technology". Is this a bug in v2.0?
