Unable to add group

I am not able to add a group it shows error already exist but I search the username it is not found.

My group unpublished due to catagory issue how can I change the catagory of the unpinned group

Hi,
If a content is unpublished, you should remove it from our directory and add again providing correct details. If you are not able to change the category of a content due to insufficient permissions and you provide its username, we can help you.
Thanks.
