I have the same issue, mine 950 has 35.000kms in twisted roads (so lots of gear change), and the problem is the ducati gearbox (nothing to do). but there are some things you can do to have a more accurate gear change.
1 - your chain slack has to be perfect the brand says 50 to 52mm from the swingarm, put the motorcycle in a stand, and rotate the tire and verify if there are changes on the slack mesure, if there is find the tighten spot and put 50mm from the center of the swingarm to the center of the chain pin. (this litle maintenance will drop the number of neutrals)
2 - you can adjust the gear lever to a down position (more near to you boot), so when you put the gear it will be less free play between your foot and the gear lever (it worked for me)
3 - keep in mind, specially if is this is your first Ducati, you cannot be gentle switching gears, you have to be hard (if you think... the most neutrals, is when you are doing a relax drive) if you are in a agressive driving might notice that are no false neutrals.
4 - even if it append to have a false neutral, always go to a upper gear, never a down gear.
good rides, stay safe
Ride safe, but always with a smile
