I setup a group of 4 cameras not working properly

I setup a grouping of 4 camera’s and the group appears on my home page. but when I click on it I get nothing. When I click the down arrow, the 4 camera show in my homepage as single units and I can see them then.
I cant figure out how to edit the group or delete it, or to get it to work.

thanks
Gman

Click on the group
Click on the gear symbol in the upper right corner
