Every time I tried to move a technique text, the spacing above increased. See the attached figures:
Fig_1 - Prior to any changes
Fig_2 - After adding senza sord
Fig_3 - After moving the text to about 1 space above the key signature
Fig_4 - After moving the text again and then hitting cntrl-z twice to get back
With each change Dorico moved the staves further apart. Certainly not the effect that I wanted.
