Tax amount range hold - Invoice tax amount does not fall within range.

Regarding the Integrated AP invoice, we are applying a 0% exempt tax rate code (tax amount is zero), yet the system is still putting the invoice on a Tax Amount Range Hold. However, this hold isn't occurring when we manually create an invoice with the same details.

Could there be an underlying reason for this, or might we have overlooked some configurations in AP or Tax? I would appreciate if anyone with experience in this area could offer their insights.
