Problem with Material batch split

To all SD experts,

I have got a problem on Credit note. The Returns order has been created followed by the returns delivery. In that return delivery, one of the material has been recorded in 2 different batches for eg. Material ZZZ quantity 100 units have been brough back as material zzz, qty 75 - batch 123 & qty 25 - batch 456. Because of batch split, goods return have been blocked & therefore I am not able to raise the credit invoice as the zero quantity is getting picked up.

Please help me in understanding if batch split can cause such a problem & the ways to rectify the same.

Thanks in advance!
