Don't worry mate, I had this problem, it was driving me mad, save volume at 12 O Clock, go away from patch and back in and it was back to 2PM again, It's in the volume pedal parameters mate. If it was saved at 100%, it will not change unti you go into amp parameter and change volume to say..70%..hit save and it is done, I only learned through trial and error, good luck, if you are struggling, I will wiz downstairs and try to give you step by step guide.
