Different battle reports-same battle!

[Big Ideas]

I have noticed a discrepincy in the battle reports in the two AARs between MrT and Barksdale. On Sept 62 of each they had a battle at Memphis.
The Union battle report shows that CS river units assisted in the battle giving the CSA forces a total of 6434 men and 169 guns and an admiral leader.
The confederate battle report did not show any naval support from nearby ironclads giving only 4561 men and 8 guns and no admiral.
The Union forces on both reports are the same.
Also the losses to both sides are also the same.

I think they are playing 1.14 vanilla
