I know that the power levels are theoretically fine.

I know that the SNR is within margins for 64QAM modulation - BUT ....

1/
I don't like only 30 dB SNR. It's poor although if you're right at the end of a trunk then there may be little that can be done about it - perhaps the nearest amplifier could be looked at.

2/
It is fairly clear that DS3, which has the poorest power level has the highest number of uncorrected codewords. This is not good.

So something is wrong IMO and it needs proper attention. The one caveat to my remarks would be to look at the stats again ajnd see if anything's changed.

Post the stats here again plus your event log (MINUS YOUR CM-MAC ADDRESS).
