I have noticed a very strange bug when positionning fingerings with slurs and substitution.
Each time I want to position fingerings relatively to staff or slur by toggling position vs staff in properties panel, the fingering (with substitution) on the note beside is moving upward indefinitely !!
Here is a Dorico file were you can easily reproduce it : just select fingerings above C and D, press several time thre toggle button position/staff in properties panel and you see that fingerings above E is moving upward.
