Da Capo performed twice when "D.C." mark is duplicated within a system

Issue type

General playback bug

Bug description

Da Capo is performed twice in a score which is based upon the Classical Orchestra template.
Attached score is an example of this. This seeems to be caused by "duplicating" the system elements to the Violin staff as in other templates and manual created scores, they only appear at the top staff.

Believe this issue applies to the other system "jump" elements as well, not just the D.C.

Esp. bad as there still is no UI for dealing with these SystemObjects:

    <SystemObjects>
      <Instance staffId="9" barNumbers="false"/>
      </SystemObjects>

Confirmed also in 4.0.
Happens because of the duplicated system objects, so not limited to the "classical orchestra" template, but in fact to any score that has D.C. replicated across a system.
