All custom post types are moved to a separate plugin (The7 Elements) from The7. ver. 3.7.0 onwards. It supposed to be installed and activated on update by default. If not please install it from The7 > Plugins > The7 Elements.
Also make sure all required modules are enabled in Dashboard > The7 > My The7 > Settings > The7 Post Types and Elements.
