Woo Hoo !
You have discovered a quirk in the Magnum custom setup. Unless the battery is discharged much lower, it will not revert to absorb on charge. The reason for this is that it brings the battery voltage up to 13.4 and the amperage is based upon whatever the battery will take at that voltage. Since your charger max amperage is 120 amps, you were getting 60% or so of the max.
In everday pedestal to pedestal use, this is of little consequence. However, now that you are aware of what it does, and you want a 100% charge, go to Control on the panel, Charger, and place it in Bulk mode. This will charge the batteries the quickest and fullest. It will revert to float when it reaches the cutoff parameters you specified.
Thank you very much for closing the loop on this problem. Your journey will likely help others in the future with similar setups.
