Missing Line Details when Import PO Receipt Entry

Hi, I have tried to import PO Receipt Entry using Single CSV file format.

The data import showing no error message. However, when I call out the receipt number, only header with data but line details showing blank.

Choosing the Single CSV file for data import.

Message showing header and line inserted and processed.

PO receipt with header but line detail is blank.

Anyone has the same issue?

Thanks.
