HX One midi input to select preset from preset list?

[caf5r]

I set up a two-button midi footswitch where the right button goes to Preset List with just one click (CC-5, Value 1), as opposed to hitting the two on-pedal switches -- this works fine, gets me to the preset list. But then I can't get the same midi footswitch to select a preset from the list, by either using CC-5/Value 1 again or Value 0 (Home), this latter surprised me because clicking the Home button on the pedal does select the preset highlighted in preset list. Using the manual, pg. 31, isn't helping me find an answer. 

 

Is there a MIDI CC+Val I'm missing that will select the preset from preset list? 

 

Thank you!
