If you got it from a home brew outfit it's unlikely it's got a siphon tube in it. With a tube you will get liquid if you pull a lot of "stuff" and gas if you pull a little. You might be moving far more volume through the second regulator.
The other possibility is water / ice / guck in the line to the second regulator. Past that the obvious one is "it's broke".
I'd email Keg Connection. You should get an email back from Nanette within a day or so with their advice.
