Strange Bass Pizz. PlayBack. - Bug ??

If I write pizz. in the bass-part, and one of the notes has a staccato or an accent (or a slur), then the sound change to arco and continue with arco. I use the preset sound for a Double Bass. A bug? I use Dorico 1.1.

This is a known bug in 1.1 which will be fixed in the next update.

Thank you very much for the answer.
