UPDATE: I was totally WRONG and do not know why my record mode solution worked because I did NOT do what I am about to explain originally which IS the solution...
So when you enter new notes into the tracks PRV it WILL create a new take lane BUT if you have Take Lanes for the track already open it will not appear. Also the new lane, at least in my case will be muted so the notes ARE indeed there. The lane is just muted. Holy crap. My notes are STILL being registered on Channel 1 instead of Channel 10 but they are indeed playing. What a mess and a total waste of an afternoon. So it is NOT depending on the recording mode. It is a matter of inputting some notes, breaking open the take lanes (or closing and reopening the take lanes) the Unmuting the new take lane.
Sorry for the confusion.
The solution offered below this vvvvvvvvvv line is NOT correct!

AAAARRRRRGHHHH!!!!
It was because of the comping mode!!! I switched it to Sound On Sound and now the new notes are working!
I have NO idea WHY that works the way it does but I figured it out by going to a completely empty area of the PRV and inputting a ton of notes to see which clip/take on the track they would appear on. The answer is NONE. They weren't showing up on the existing clips but WERE showing up in the parent track BUT not creating a new lane or a new clip in the take lanes area.
It made no sense so just by total fluke and because it had solved previous weirdness I was experiencing while tracking in X3 using Comp Mode I switched to the old Sound On Sound.
TADA!!! Inputted notes sounding properly. At least they did just a second ago.
Good god that took WAY too long to figure out. I'll "laugh" about it in a couple hours but right now between that and the non stop freaking dance music I've been blasted with from my neighbors the past few days I feel like I'm ready for the funny farm... well more so than usual.
Anyway, thanks for bearing with me guys and if you see anyone encountering this issue tell them to try disabling Comp Mode. I cannot explain WHY it works but it does.
Cheers.
