When templates are deactivated, they still show for non-admin users who the template was shared with. This is very confusing for our users and allows them to choose a deactivated template when creating a project. To prevent this, when I deactivate a template I also have to un-share it will all non-admin users, and this is an extra step that I don't think should happen. If a template is deactivated, I think it shouldn't show up for users.
