Speed sync error with cruise control

[SiGmAX666]

When using long-press of the cruise control buttons, the MPH increases/decreases 5mph at a time. Using op4 0.8.9, the speed is rapidly reset to where it was before. Using short-press, you can change the speed 1mph at a time successfully.

Is there a workaround for this?

If you watch the below linked video you'll see the speed jump down 5mph at a time, and then rapidly count back up - the 5mph down at a time is me via buttons, the increase is automatic from OP.
