Solar panels generate power. Power is expressed in watts. This power is carried over the wires as current. Current is express as amps.
In electricity there is a formula:
Watts = Volts X Amps
So if you have 120 watts, it could show up as:
120 Watts = 12 volts X 10 amps
or it could show up as:
120 Watts = 120 volts a 1 amp
In both cases, the power is the same (120 watts) but the current is very different (1 amp vs 10 amps).
In your specific example, the solar panels are creating 463 watts:
463 = 29.5 X 15.7
This is what enters your MPPT charge control.
The charge control then converts the voltage from 29.5 to 14.3, which is what you need to properly charge your batteries. But the power (watts) does not change (other than efficiency/inefficiency factors, which we will ignore).
Notice that
466 = 14.3 X 32.6
Your power hasn't changed.
The lesson, do not confuse AMPS with POWER. Amps alone do not give any indication of power, until you also know the voltage.
