Customer Group Selection on Discount Rules Not Working

Since changing to the drop down box for Customer group selection in the Discount rule set-up, I am unable to select ANYTHING but the "Not Logged In" and get it to stick!
Every time another option is selected, such as general, vip, wholesale, etc. it will show up in the box, but after saving it reverts back to only "not logged in".
I have verified that the discount code I have set up does work if the customer is not logged in, but for obvious reasons we need to be able to set it to be allowed for use with any/all customer groups.
Thanks,
