the problem could be FCSystemStaves (probably you use it for
calculating the staff system height based on its distances).<br>
I noticed that FCSystemStaves doesn't include staves if they are set
to "cut away" or "in Score only (Collapse)". But it does include
them when they are set to "collapse" - so although the staff is then
invisible in the staff system it counts as a system staff.<br>
<br>
That means: if the "last staff" in a staff system is set to
"collapse" it is still included in FCSystemStaves and thus also
taken into account for CalcHeight. This returns a staff system
height which doesn't match the actual staff system height.<br>
