Difficulty finding neutral at a stop is caused by the clutch plates dragging due to insufficient separation. The root cause is usually air in the hydraulics — so as a first step you need to bleed the air from the system.
A little clutch dragging causes that. The Ducati Master cyl./Slave cyl. combination doesn't give you much, if any, extra lift so even in a properly bled system it can be borderline/troublesome. On a new clutch pack there is one plate that is a spring plate, it's there to soften the 'take-up'. That plate soon gives up and becomes flat. That's when you get clutch 'squack'. I started out in the British motorcycle industry and their clutches always dragged. Years (many) ago I developed the habit of finding neutral while the bike is still rolling and it works for my 851 to this day.
