Sorry, I know this a late reply and this beer is long gone but I figured I would chime in just incase it happens again in the future. First thing I would have done is tried to increase your head pressure. Not sure what your tanks are rated for, but 9psi seems pretty like pretty low head pressure for carbing up a beer. We typically have our brite tank head pressure between 14-18psi, when carbing, and once its carbed up, we set the pressure based on ABV. McDantim EasyBlend app is really good for determining head pressure vs ABV. If we drop below 8psi, it will actually scrub out co2 from solution.

Subject: What to do when your carb stone fails...?
Hello!
After much staring, head scratching and various attempts to figure this out. I thought I should ask here.
The Issue- I am 99.9% sure that the gasket between the carb stone and it's housing on the brite tank has failed, causing the CO2 to leak before it goes through the stone resulting in bubbles too large to go in to solution. I am 99.9% certain that this is the problem, as I can hear the bubbles through the wall, and the head pressure goes right up whilst the beer stays uncarbonated.
I have tried putting my O2 stone in a site glass at the input/output port of the brite, head pressure at 9psi, and set the incoming pressure to just where I can see bubble coming through the glass. Unfortunately this just causes the beer in the site glass to foam up and pushes all the beer out, causing large bubble of CO2 to go up through the tank's fill level site glass. Which... is just adding top pressure to the tank, not carbonating the beer.
My FV's are all full...otherwise I would just transfer over and fix the stone in the brite.
Details- 9.5bbls of beer at 31 degrees F. I have the carb stone in the tank, a sample port and the access from the bottom of the dish, currently a 1.5" globe valve on there.
Any ideas?
Thanks!
