Aux Track - Automation Mode - Display

Hi,

As we know, if wanna show up Aux Track on Arrange Window for Automation, a click on Automation Mode in Mixer Window then I'll show up accordingly! Still, it'll lined up according to the Arrange Window displayed on Mixer Window (Tracks View Mode) as well.

Yet, if we have done the automation then delete the Aux Track, it'll disappeared from the Arrange Window, but it'll still remain in the Mixer Window. In fact, it'll then return to where it originally live at!

Question:

* Most of my Aux Track worked as what mentioned above nicely! But, only 1 Aux Track DOES NOT work as proper as it suppose to!

* What was happening? After automated the Aux Track in Arrange Window, then I just delete the track as usual (backspace key on keyboard). Aux Track disappeared from Arrange Window, as well as disappeared in Mixer Window (Tracks and All Mode). Shocked me! Immediately I "UNDO" the delete step, Aux Track returned then!

What's the problem? Yup, only the specific Aux Track has problem! Need Help!

Thanks!
