Group member veiwing issue

Ok I'll just start out by saying I don't know if theirs another post somewhere answering the question I'm about to ask. If so I haven't come across it yet.
I started a group a while back to find members in my area and start conections with them. I haven't been on in a while, but according to the site info my group has 120 members. However, my group profile only shows a handfull of these members, so I have no idea who the vast majority of them are or anything about them. Which makes the group kind of pointless.
Does anyone know what I should do about it?
