FIFO count frozen on MPU6050

I'm trying to get the FIFO acceleration buffer to work on MPU6050 according to the driver eMD 6.12 using HAL library.
The thing is that whenever I perform a read operation from FIFO_COUNT register, the FIFO count is frozen at 1024 although the FIFO overflow occurs constantly. I've spent an amount of time reviewing my code and don't see any anomaly on it. Any tips on that?
