Mussels - my 3A charger (14Ah battery) does exactly the same thing.
Charges until the green light comes on. Switch off. Wait a bit, switch it back on, red light and orange light - then after a few seconds the orange light goes green indicating the battery is charged.
I had assumed that the BMS was telling the charger that the cells were already charged, so the charger switches to trickle charge so the BMS can balance the cells (again I am assuming about the trickle charge - I haven't put a meter on it to check that that is what it is doing).
