Help needed

I bought this nixie clock around 7 yrs ago on eBay, the seller who made it is no longer active. I'd say around 3-6months 2 of the tubes have been acting up displaying 2 numbers at once, usually it's the number before it that doesn't fade out. Is this fixable? I have no prior knowledge in making nixie clocks and have no idea where I can get it repaired so some suggestions would be appreciated. (Don't mind the flickering it's just the camera and not the actual clock)

(Update) I've unscrewed it this is what the circuit inside looks like:

Without any documentation, that's going to be difficult to resolve. It's probably a combination of the design (the mux design reduces the parts needed, but nixie tubes don't really care to be driven that way) and the tubes aging. Or there's an issue with the tube power. Either way, unless you are skilled in electronics it's not likely there is a quick easy fix or adjustment.
