Problem saving a new version of Factory Content

I have tried and tried to just change the speed modifier of the rotary speaker effect on the “Pale Shade” patch in the HALion Fatory Content program from the MOD wheel to my Footswitch pedal on my MIDI controller. I change it, I saved it under another name. Every time I bring that new patch back up, it’s as if I didn’t make any changes. And yes, the program lock is off. HELP!
