I'm not to clear on everything you're describing, but I can say this much:
First, you most certainly can assign trackers in narrowband. The only time this has ever been a problem for me is when the TA is going through a turn. I can't imagine why you haven't been able to assign a tracker in NB. Maybe you had the sim paused, or something wierd like that?
Second, you might be right about BB trackers not showing in NB. I don't know for sure because, despite all my years of playing SC and DW, I always go the other way--first contact on NB, then BB if I need it later (for DEMON). Maybe they didn't set it up for BB trackers to show in NB. But, have you tried the "tracker review" button? That might snap the cursor right to your contact.
