"floating" rehearsal marks upon extracting

[Neil Wyles]

Am I doing something wrong?

I have arranged a medley for concert band and have lots of rehearsal marks.....and when I extract, they are all over the place in the parts....usually within a few bars of where they belong.

I have tried dragging the marks into the bar before extracting to hopefully "lock" it into place, but this does not work.

It is not a huge deal, but it does take lots of time when correcting 25 different parts for various other things, and I would like to solve this if possible.
