How did you set up the other charge? Go examine that item setup. You have to open up both sides of the other charge item so it posts to both a sale and a purchase with different accounts for each side. Always check your items are completely set up. 

One way to check your item set up is to run an item report and add columns to make it easy to check all your items are pointed at the right accounts on both sides as in both sales and purchases. This is often overlooked. Another is to run a report by clicking on the bottom line of your income statement to see a detailed listing of each category and check that there are debits where they are supposed to be and credits usually only in income accounts. I’ve seen item lists so poorly maintained that this report has debits in income and credits in expenses completely messing up the lines on the income statement. Understating sales and understating expenses is to be avoided. 

Btw when you correct the items it will ask if you want to adjust the historical entries. Be very careful here. If you’ve closed a year end and have inventory items it’s likely going to adjust your COGS and your inventory balances. Not a good outcome! Unless you’re watching carefully your prior year end balances will be affected and you will not be able to reverse that outcome. Check your balance sheet year over year to make sure it wouldn’t be affected before choosing to adjust history.
