MIRO - Line item proposal - GR lines already processed

Hi Experts,

When doing MIRO we are observing that system proposes the same line twice once with line values from recent GR + it also shows line items with amount and quantity = Null which have already been invoice before.

We have recently activated BF: LOG_MAA_1 and i believe this behavior is coming from that BF.

I am not able to find any notes around this, please share your experience and fix you may have already applied.

Screen shot attached.

Thanks in Advance.
