XNAT-4298 Fixed 3rd part of the bug by simply removing the checkboxes from the modals. They will default to enabled when created, and if someone wants to disable them, they can do so from the main page. I don't see the need to have them in the modals as well, but they can be added back in if we can get an onclick handler added to modal checkboxes like we have for non-modal checkboxes.
