Facebook group missing

Hi there,

I am sharing my Facebook page contents to many groups that I am member of. I can share to all the groups but one. This one is named Star Wars and I am a member of the group. I think the problem is that I am member of several groups that start with 'Star Wars' name and when I type these words only 10 groups are showing in the list to be selected and none is the Star Wars group. This group is important to me because it is the one with the larger number of members. Any ideas how to solve this?
