Bad scripting in Chamber Strings Cello Legato (Bowed)

Around C#2 to E2, when playing a legato interval with mod up towards the top I'm getting a pop after the note change. Only down around those notes. Does not happen on the Legato (Fingered). I'm using v1.4.1 of the instrument. Do you think there is a problem here or is this just a leftover glitch that hasn't been sorted?
