NotePerformer NPPE with BBCSO Core - accents?

I hope it’s OK to make a new thread instead of going onto the giga NP4 thread. The new 4.1 update is fabulous! But I’m noticing with the string accents in NPPE with BBCSO Core, that they almost sound like a pizzicato doubled with an accent, at least some of the time. Here is a short file and mp3. Has anyone else noticed this?
