FWIW, I would say your issue is your upstream pwr not downstream. 54 is too high. Also your after pic shows channel bonding which is not there in the before pic.
You can remove any excess splitters and check all the connections to make sure they are good or call for service.

I agree. Those upstream power levels are to high.

As mentioned, your upstream levels are too high. 54dB is the maximum for 2-channel bonding.

FWIW, I've seen problems at 50-51 dB even for two channel bonding. This is not an exact science. Hardware and local system specs vary as does the actual accuracy of an given modem's measuring mechanism. Inaccuracies of 2-4 dB are always possible.
