If that issue of 8 vs. 7 means your command numbering is one off from the encoded value, you can make all the button numbers right by using this change to the .irp file:

device=0
function=0..60
Frequency=39100
TimeBase=205
Zero=1,-3
One=3,-1
Form=;16,-8,D:4,(F-1):8,-36200u

I used 0..60 instead of 1..60 because IrPanels.exe doesn't work without a function 0. Even though you don't seem to want a button 0 you need to give IrPanels.exe data to create one.
