I just did a quick test using Aria and J&BB. In my test CC7 did nothing, that is no sound what-so-ever until I moved the mod wheel (CC2). All of the volume changes were controlled by CC2 not CC7. Note that I don't have Finale so I can't test using it.
Try going to process and click on find/change and change all of the CC7s to CC2's and see what happens. Of course do this on a copy and not on your only version.
Let us know how you make out.
PS - Susan beat me to the engine and player version thing. Try that also.
