Reoccurring Errors on Invoice (AP)

[manav]

I have attached the document showing the reoccurring errors for invoice
It appears to come from the Freight charges added to the invoice.

The following information is the distributions exported into excel. I have highlighted the error of freight charges in question.
Pls let me know why it's happening and fixed
