What does blinking LEDs mean for GE DFCI AFCI/GFCI Breaker
According to the manual..

Clearing Last Known Trip Condition
The last known trip condition can be cleared by the following process: 
 1. Turn the DFCI to the “OFF” position.
 2. Press and hold the Push-to-Test (PTT) button.
 3. Turn the DFCI to the “ON” position.
 4. Release the PTT button after 3 seconds.

After clearing last known trip condition the breaker should stay on work properly.

If that doesn't work there is a good chance a device on the circuit is bad or the wiring has a fault to ground. Less likely problem could be a bad breaker but probably not in this case.
