MIRO reversal split the value between GR/IR clearing and 3rd party material account

Question

Dear Team,
We are facing the issue in MR8M for PO 4500002602; the PO has been created on 11/30/2012 in the previous fiscal year and performed the GR and IV in the 2013 fiscal year.
For one GR the accounting flow is as follows:
For the 3 GR's 5000013746, 5000013747 and 5000013748 one IV has been done 5105612646, at the time of IV the account entry is as follows
GR accounting entry:

But for the same IV when user reversed with MR8M system split the GR/IR cost as follows:

778.60-
750090
1100
Sales Tax
55.01-
216200

55.01
One line item at the time of MIRO i.e. 3357.38 is split into two line items i.e. 3245.65 and 111.73 in reversal.
But in quality system when we create new PO, GR and IV system is working fine why in case of previous year PO system is behaving like this.
Kindly advice.

Ravi
