I think it has to do with the user presets being created before a flash memory update. I had the same issue on my X3 Pro. It also made the X3 restart when I accidentally hit preset 32A on the FBV as I found out during a gig (yikes). Looking into it more at home the restarts happened when selecting ppreses over 8 which in Gearbox all gave the message to upgrade to 2.0. I fixed by reflashing. Fist to fhe latest version which didn't work. Then to the oldest version which did work then back to the latest. Select to not keep your old sounds during the process. Save your old sounds before the reflash process and after you are done load the bundle you saved and select only the presets you need and send to the X3. Worked cor me. Hope this helps.
