Would you check the problem of BLE mini for 2 motor? and When will I meet the upgraded BLE mini ?

I'm using the Romeo BLE mini for 2 motor control.

But I found the problem like below.

Romeo_m.motorControl(Forward,100,Forward,0); M1 is turn on, but M2 is also turn on
Romeo_m.motorControl(Reverse,100,Forward,0); M1 is turn on, but M2 is also turn on
Romeo_m.motorControl(Reverse,0,Forward,100); M1 is turn off, but M2 is also turn off.
Romeo_m.motorControl(Forward,0,Forward,100); M1 is turn off, but M2 is also turn off.

What happened in the driver?

and

How can I use Romeo BLE mini for two motor control correctly?

and When will I meet the upgraded BLE mini ?
