Tailf:cli-incomplete-show-path doesn't work

Following is my YANG code. Although I used cli-incomplete-show-path
It gives the option for after feature_show.
Any idea what should I do?

      *container feature_show {*
*         tailf:info "Show feature information";*
*         tailf:cli-drop-node-name;*
*         config false;*
*         tailf:callpoint feature_show;     *
*         tailf:cli-incomplete-show-path;*
*         *
*         container sessions {*
*            tailf:info "Show feature Sessions";*
*            container brief*
*            {*
*                tailf:cli-full-show-path;*
