Wrong Vertical Positioning of Dynamics

In all latest nightlies there is a bug in positioning of dynamics.
Vertical position is correctly placed - as in text style defined ->only in top staff of the score.
In all lower staffs the dynamics are placed too low.

As more staffs a score contains as lower comes the positioning in lower staffs.
It seems MuseScore doubles the amount of vertical positioning.

This bug concernes drag & drop function and
double-click in palette icons for marked notes.

Tests are on a WIN XP system.
