Can’t Show Dashboard Widgets After They’ve Been Hidden

I have used AGCA to hide certain admin dashboard items from other users. I hid some dashboard widgets under “screen options” by accident, but now I can’t get them to show again. When I check the box under “Screen Options” and come back again, the box is unchecked. I can’t get the widgets back!
