I assume that is on the Broadband.
Take the same contact, go to the Narrowband. Go to the bearing of the contact, then click the screen on the first frequency line, then try to assign a tracker.
For the Broadband of the sphere array, yes there is a problem assigning trackers if the SNR is lower enough, but if it is above 8 or so (on the SW, other subs require a lower SNR... that's the nature of the bug), then it should work.
Other than the sphere array Broadband, all sensors should appear to function exactly the same with or without the mod.
And the changes related to the sonar have been around for some time (four months or more), so plenty of eyes have seen it work.
I hope this works for you.
