Expectations for 6 volt batteries
We replaced our two 12V group 24's with two 6 volt golf cart batteries - 220 amp hours. We also have 270 watts of solar, a Trimetric monitor and a Progressive Dynamic 9100 converter with a Charge Wiza...

Your 6v batts will get you more AH (220 say) than the two 12s (160?) so that is not the problem
You have a draw somewhere. That 13.4v does not means your batteries are charged. That means they are just getting charged on the way from 12.x in the morning to 14.x in the afternoon. Whether they ever get fully charged (12.7 resting) depends on how much daylight is left after they get to 14.x and can do the absorption stage before dropping to float voltage of 13.8 whatever the set point is for that.
You need to watch the Trimetric amps and see if amps are negative net when they should be positive. Say your solar is adding 10amps, you have a 5amp draw, you will see 5 amps charging showing. If you have more draw than incoming, down it goes.
