Help ! Assembling CO2 bubble counter

I have a MuFan CO2 regulator fixed to a 2kg CO2 cylinder and had set the bubble count to 1.3 bps. Am using an inline diffuser on the output flow. Also have a check valve (steel) in place between the regulator and the inline diffuser. This has all been working fine since a few months.
Since a couple of days I noticed that water has travelled back and through the check valve all the way to the CO2 regulator and since then I have been observing that my bps reduces significantly even though I haven't changed the setting on the needle valve.
I tried increasing the bps again to 1.3 bps but after a day or two it again drops to roughly 0.2 bps.
Maybe the water entering the regulator may have caused this. I started disassembling the regulator and bubble counter to clean it.
There was a small spring and a black rubber stopper of some sort that just popped out while disassembling the bubble counter.
Now while trying to put the bubble counter together I have no idea where the spring and the black stopper needs to go 🤔
Here is a pic of the regulator and the bubble counter.

Am not quite sure what fits where now 😬

The CO2 has been turned off since a day now and the check valve doesn't seem to stop the water to flow back to the regulator.

Does the mean that there is something faulty with the check valve and if so can it be repaired/fixed ?

Might need to do a service on it bud, you can find them on YouTube, including setup and fault finding. Good Luck👍
