On the telrad end. There is a trunck setting. if you sb5 or lower it's long or short. on sb6 and higher it's short long and very long. If it set to short put it up to long or very long. It's where the truncks are programed on the col or chl or mpd card. You must reset the system after this change to take affect. Also when you make this change the truncks will drop right after the download.
