order email send to multiple customer(random customer)

Question

My problem is ordered email send to random multiple customers, i have installed Magento(Magento ver. 1.9.3.8).

when customer place order, it will send an order email to random multiple customers. it sends order email to the customer(who order product) + random multiple customers. each and every time Magento send order email to a random customer. I do not have any file or folder in local(app\code\local)

I did clear index, Cache Storage Management, manually Cache clear(from var), flush Cache etc..

I have no idea how to fix it, Any help or suggestion will be appreciated.
