Joe, on the HC, touch Delete, and go to the SW800. Touch Sound, and see if the 567ULT is listed. If it is, touch Cancel. The problem is then in the HC settings for that engine. If it is not listed you have to copy it again from the HC.
Assuming the file is there, go to the button settings page on the HC and take another look at the prime mover button settings, making sure they are the same as the ones for the GP30. I’m sure you’ll find the problem.
