Muse Strings Violin 1 playback problem

Not sure if this has been reported earlier - but I'm finding a quirky playback problem when using Violin 1 of Muse Strings. The attached score has one line, with eight notes in the first measure descending to quarter notes in measure 2:

When played with Muse Strings Violin 1, the first note of the second measure sounds as an eight note, followed by a dotted quarter (which is incorrect). When switching playback to either Muse Strings Violin 2 or MS Basic, the rhythm is correct. MP3 files showing the three playback options are included in the attached zip file. All rendering examples done using v4.0.1.
