I found the problem in AP invoice after apply the GST code and Validate the invoice than apply on Pa

I found the problem in AP invoice after apply the GST code and Validate the invoice than apply on Payment witholding Tax on Item amount. System deducted the witholding tax on both on item as well as GST amount.e.g: if Rs.100 is the item amount. And we apply GST 16% the calculated GST is Rs.16. And 1% witholding is RS. 1 but the system deducted is Rs.1.16. The amount Rs.0.16 is the amount which is calculated on GST amount which is wrong calculation.

Suggestion Required
