Facebook Group Problem! [HELP]

OK as the title says I recently encountered a problem while adding friends to my facebook group.

Previously I could directly add friends to my group, but now, it seems like facebook is sending invitations to join the group instead of adding them when I want to add.

I tried to add friends in other groups and its working like it should, seems the problem is my group.

This is my first group so I have no previous experience with facebook groups!

Does anybody know what is the problem? Can it…
