Billing has a wrong "Receipt for Payment"


Checking Fron Office Receipts, they’re all ok.
So CLICK ON last patient RECEIPT to see details

TOTAL amount 30.00 is ok
those two WRONG lines are included

(Price : -60 , Qty : -800 , Total : 48000)
(Price : -3000, Qty : -1000, Total 3000000)

They have no relation to that RECEIPT

Check another RECEIPT report to check its integrity on 30.00 payment

and it’s ok

Checking my DB I’ve located those RECORDS on TABLE : DRUG_SALES

Initially my pharmacy used to get stock but no now

I guess RECEIPT 's SQL Query must be checked

OpenEMR Version
I’m using OpenEMR version 7.1

Any idea or comment
