Impressive strings, with glitchy issues

I wrote a miniature orchestral piece to try out composing with MuseScore 4's strings. The sound is pretty impressive overall, and the experience motivating, but there are abrupt transitions and truncated sounds, and it's challenging to manage some expression with velocity shunted to the side and dynamics only—hence the number of dynamics peppered in the score.

You can listen and download it here in score where I've annotated the issues in place.

Side note

I suppose the following should go into a separate post, but it also pertains to the strings sound library, so here goes. During editing, on clicking a note, I hear an unpleasant swell at the tail of the "preview."

Start by listening to the annotated score and downloading it from the linked MuseScore page, then reproduce the abrupt transitions, truncated sounds, and note-preview swell on macOS Ventura 13.1 with MuseScore 4.0.1. No source files or tests are identified, so the issue is complete only when the reported string-library playback and preview problems have been isolated and corrected.
