Copy bar with dynamic double up the dynamic.
When you copy a bar that has a dynamic into a bar that already has a dynamic, the dynamic is doubled. If for example I am copying a few bars with lyrics into the identical score without lyrics, at the identical measure (when I am creating for example a version with dynamics disabled i.i. all set to 90) the dynamic from the source is copied into the target but does not remove the target, in other words the measure is not 'cleaned' before the copy is dumped.
