My setup

JR11X 2.4 radio with EzUHF external Tx.
EzUHF 8 channel lite receiver
Both are updated to 1.52 FW

After binding successfully and initializing the Wizard sequence I noticed both my Throttle and Aileron channels swapped. I then opened Immersion Tools and remapped the following.

PPM1 - CH1 ---> CH3
PPM3 - CH3 ---> CH1

Controls work as expected now.

Any idea why this occurred?
