Solo Strings Issues

I was playing back an older piece of mine and every time there is an instance of staccato in the higher registers it clicks.
It's kind of a cool sound but...not when I want strings.
I'm attaching a sample of my String Quartet and then just an isolation of the most obvious bit (Viola)
