Samsung :: R451C - Contacts - Groups

I'm new to this phone and have input 100 or so contacts by hand and now wanted to sort them into groups. I created the groups I wanted but when I tried to input the contacts to "Friends" I got the message that groups cannot have more than 10 entries. Can this be right? I can't find a setting to change this but it makes no sense. What's the point of groups if they're limited to 10 entries? This could be a make or break for this phone for me. Once I add all the contacts, I can't imagine scrolling thru all of them trying to remember how I input a customer's/friend's/tenant's/etc name.
