@TB3dock No, "create component" "create template" and "create Dialog" menu items are NOT removed from crx/de.
Although, admin should have all the required permissions/ACLs on these nodes but could you please check if the modify action is enabled for admin or administrator group? Is it happening for all the nodes/folders under /apps?
Also could you please try to create a new user, add this user to the administrator group and try creating the component/template.
