In the process creation events

There is an email event https://hte.crm-onebox.com/admin/shop/event/1837/ The client wrote to the company's mail, that is, the client wrote to us. If I turn on the Turn a letter into a process action, a process will be created and the client of the process will be the one who wrote to me, that is, the sender of the letter. But if I go into the event and manually click Turn it into a process, it puts me as a client, that is, the one who received the letter https://prnt.sc/xppacw https://prnt.sc/xppapa And this is not true, it is necessary that the person who wrote the letter puts the client, as well as in action to turn the letter into a process. How to fix it?
