Planned Delivery Cost in MIRO for different freight vendor

Hi,

Kindly share, how to get rid of above issue:

1) PO created with a freight condition (FRA1 with a different vendor assigned to it under item conditions tab)

2) GR done, & all accounting entries were OK, (including freight costs in FR1 or FR3)

3) while doing MIRO with selection Planned-Delivery-Cost, Amount & Qty fields are "Blank" and auto flowing from Clearing A/cs

I found this error in both Domestic or Import POs.

I've read many threads, but could not find a clear solutions for the same.

Plz help
