Pizzicato Problem

I am having an issue with a score created in 1.3 which I've been fine-tuning in 2.0.

The pizzicato in the VC/VdG line at measure 39 in the third movement wasn't working at all, even though it had worked fine in 1.3...and still did when I opened the unmodified 1.3 score in 2.0. It took me about three hours to conclude that the problem was with the sound-font...but now I'm not so sure. This whole thing is pretty confusing, so I'll do my best to explain what's going on.

There are four scores attached.

The score entitled Mvt III 1.3 UNMODIFIED was created in 1.3 and never opened in 2.0 or modified in any way. The score entitled Mvt III was created in 1.3, and tweaked in numerous ways using 2.0. In both those scores, the pizzicato works fine. In the tweaked 'Mvt III' score, the pizzicato worked no matter what I did to the score, including reformat the text and music, change sounds in the mixer, or even change instruments in Staff Properties. (In the original 1.3 files, I'd been using Tim; in 2.0 the soundfont had defaulted to Fluid but I had added Tim later and was using the cello sound from Fluid and the recorder sounds from Tim.)

The third and fourth scores attached are composites of three separate 1.3 files (including Mvt III 1.3 UNMODIFIED). The composite was created by appending empty measures to the original Mvt I file, and then copy/pasting the music from the Mvt II and Mvt III files into it. All that was done in 2.0. The composite score was then saved in 2.0 as Mvt I-III, and I had been tweaking the formatting of the text and music for a few days, getting it ready for publication.

Note that I messed with the soundfonts after creating the composite. Since it was playing in 2.0, it was using the Fluid soundfont (which has really horrid recorder sounds), but after Jojo and Marc explained to me how to do it, I loaded the Tim soundfont and set the recorder tracks to play in that. I set the viola da gamba track to use the cello sound from Fluid.

In the score entitled Mvt I-III C, I have changed the instrument from VdG to Cello, and the pizzicato works. A kludge solution, but a solution nonetheless.

The last score attached is entitled Mvt I-III VdG. This is the one that shows the problem. The instrument choice for the bottom line in all three of the original 1.3 files was viola da gamba. In all three original scores (created in 1.3) that automatically gave me three viola da gamba instrument choices (channels??) in the F10 mixer: Viola da gamba, viola da gamba-pizzicato, and viola da gamba-tremolo. (I chose to use the 'cello' sound for all three of them.) But when those three scores were combined into this file, the two additional VdG 'channels' disappeared...and the pizzicato won't play.

I did not (at first) notice that the instrument list in the F10 mixer no longer contained the pizzicato and tremolo instruments, and I am not even certain at what point that happened. It was only today, when I noticed that the pizzicato section at measure 245 (shown as m. 39 in movement III) would not play as pizzicato, that I realised that. When it didn't play properly, I clicked on the staff text 'pizz.' and opened the text properties menu...but when I attempted to change the channel, the only choice available to me was normal.

I have been pulling my hair out ever since trying to figure this out. In the end, I changed the instrument on that line from 'viola da gamba' to 'cello', and that brought back the two additional 'instruments' (pizzicato and tremolo) in the mixer. So I have kludged a solution but still have no explanation for--or understanding of--what's going on.

Any thoughts on this mess?
