Minus in inventory movement of quantity report

I’ve found some error in inventory movement quantity report. I attached this screenshot below

It shows minus in purchase, but actually the minus quantity are from the selling that we use from inventory kit.

please your guidance

This report has been designed before introduction of inventory kits. I’m aware of this issue. There will be a new column to split the amounts so it’s clear what was manufactured, purchased and sold.

thank you sir,
