Don't I feel silly now...... Sorry brain fart.
I had the single press issue when setting up a pivos Xios. I learned the commands from a harmony remote. I resolved it by redoing the commands using the universal browser and inputting the pronto hex codes.
I have no idea what the harmony was adding in but those codes would not work for repeat. I'd suggest trying to use pro to hex codes and see if that helps.
