Starting from 2.1.2pb release of Sobol's NEOMAN Pack, Sobol replaced the destination displays the buses use. They no longer had support for full K++ display logic - I don't know if it will stay like that or will there be option to have them back via setvar.
However for now I've made my our small patch, that brings back the K++ destination display functionality.
