If in [Settings]/[Distribution]-tab-[Permissions] and if one clicks the button [Reset Article Permission] then all previous articles are set to that permission. However, in [Submissions][Archives] select [view submission] of an archived article and click [schedule for publishing] the check box that enabled the permission is unchecked.
So by clicking [Reset Article Permission] all copyright notices of past articles are removed from the article page and one needs to manually reset each and every archived article. If that is the intended functionality could we have a [Set Article Permission] to make a global change.
