That is not too good news.
That was the main reason why we forced our users to update the device soonest as possible to the latest release, because with the new firmware release that issue can solved. As I seen correctly that v2016 firmware is some of the very first releases from October 2014.
The best thing what you can do, please contact with your distributor where you bought the device and explain them the same thing what you wrote here.
If you need further assistance in this matter please do not hesitate to contact with us in support_at_cymaticaudio_dot_com
Sorry for the inconveniences.
