Ever since the paging support was added to Connections Manger, you can no longer apply permissions by selecting the column header (scout).
There are two bugs:
You get an error saying that you do not have permission to modify connections if YOUR adult record is not one of the rows on that page.
If you do modify connections for a column from the page your record is on, it does not apply the changes to all pages.
(Note: The Feature Extension’s Permission by Position feature is broken as well since paging support was added. I have posted about that in the Feature Extension forum.)
