Beer in air line during force carbonation

I just bought the new kegging kit and kegged my first batch tonight. I decided to try the faster “shake” method of force carbonation. After I finished shaking I noticed that some of the beer had crept into the air line. It couldnt find an unsecure connection or anything like that and was wandering what would cause this and if anyone else has experienced this? Maybe I have a faulty ball valve. As I understand it, it should be a check valve that wouldn’t let anything in. I was able to clear the line by opening the pressure releif valve real quick while holding the co2 tank above the keg.

The pressure inside the keg was greater than coming out of the regulator.

Even with a check valve you can get beer in the line if the pressure between the keg and the check valve is less than the pressure in the keg. Shaking can make this problem show up more than just leaving the gas hooked up. You’ll also sometimes see it if you carbonate through the beverage post once the keg comes to equilibrium.
