I don't think you're doing anything wrong. But I wonder if it's because your sequencer is still playing and sending that CC to the X3 Live?
Does the X3 Live function as expected (meaning when you change program/patches you can still view the LCD display of the patch name, etc.) if you stop the playback of your MIDI sequencer?
What you are experiencing is equivalent to hitting the BANK UP or DOWN button once, then, hitting the TAP switch (which produces CC# 64) before selecting a channel. It will take you out of the BANK Select view and take you back to the HOME screen.
There is nothing wrong with the POD, it is just reacting to what you are sending it.
