Bug with 3.6 - Hidden staff clef changes from other parts appearing in top staff of visible system

Hello,

Firstly, thank you for the new 3.6 version. I've now been able to make some of my scores look amazing with the new vertical justification option.

And, I've noticed a bug when I've moved scores into the new vertical justification format.

When I've hidden staffs for the score, if there's been a clef change in a hidden part at the end of a system (X), the new clef for the part in the next system (Y) sometimes appears in the top staff at the end of the previous system (X).

There are some examples in this score, which I moved into vertical justification:

At the end of bar 8, a bass clef appears in the top (Oboe) part at the end of the bar. This is actually a bass clef change for the hidden Piano part, which appears in the next system.

Similarly, at the end of bar 74, a tenor clef appears in the top (Flute) part at the end of the bar. This is actually a tenor clef change for the hidden Bassoon part, which appears in the next system.

Now, I've a couple of workarounds
1. I could make courtesy clefs invisible - and that would also make visible staff clef changes for parts in both systems only appear in the next system too, which isn't ideal.
2. I could make each of these misplaced clefs invisible - and that would take time, which again isn't ideal.

Any ideas/suggestions would be most welcome.
Thanks
Derek
