Drum Map Tip Plus Key Bindings Question

Greetings; I've been having problems using prefab drum maps -- i.e. i have Battery and BFD Eco, and there are alot of Sonar pre-made maps correponding to presets for these drum plugins.
 
The problem is, when i open a pre-made map, the midi output is always assigned to a hardware midi out, rather than to the drum VSTi, meaning i'd have to change this output assignment manually, line by line.
 
But i've discovered that it's possible to change several lines worth of output assignment and/or midi channel in one go. Highlite the column you want to change and then, while holding down CTRL-SHIFT, make your selection. All of the midi outputs or midi channel assignments in the column will change at once. This is a huge time saver (found via much trial and more error).
 
As for my question, I don't know if this is a Sonar issue, or an X1 issue, but some of my key bindings are not working consistently, especially in the PRV.
 
I've assigned CTRL-ALT-Numberpad-7/-8 to control horizontal track zoom in/out in PRV; sometimes these hotkeys work, other times they don't. I can't find any pattern here; whether or not these hot keys work seems random. Am i missing something?
 
Also in PRV, i've assigned ALT-T to pull up the track manager in PRV. When i open PRV, this hotkey will work, but it will only work once. If i try to reuse this hotkey a few minutes later, it does nothing.
 
These are minor issues at worst, but it would be great if someone could point me in the right direction. The horizontal track zoom hotkeys might be working a little more consistently since i installed X1b yesterday, but definitely the issue is not fixed. 
 
Regards
Glenn
