JP1 Remotes

I am trying to create a custom upgrade for my Yamaha RX-V475 receiver and upload it to my URC 7960. I've learned 8 different commands (the 5 discrete HDMI inputs from the RX-V475 remote, vol +/- and power toggle) and copied down their EFCs from the Learned Signals.

Since their protocol in the Learned Signals tab was NEC1-y1, I used the NEC 4DEV Yamaha Combo protocol. I entered the 2 subdevices from the Learned Signals which were 122 and 126. For the functions, I entered the EFCs from the Learned Signals, changing the Y Style to y1 for all signals detected as NEC y1. Upon saving and upgrading the remote, only the Vol+/- keys work.

If I use a second learning remote (1056B01-L) to learn from my custom upgraded 7960, under learned signals it states:
"Malformed Signal: burst table extends beyond end of hex".

Here are the learned signals:

And here is my (failing) upgrade:

I've been through a bunch of threads and have tried upgrades for other RX-V receivers but none seem to do anything.

This is my first foray into JP1 so I apologize if there is anything I've forgotten. I'm happy to provide any additional details that may help.

Use the OBCs. EFCs are numbers for simple protocols, and won't work on variations on executors.

Yep that did it. Told you I was a beginner! Thanks!
