How to remove duplicate emails from Spark email client?

Question

Email

I have added 2 mailboxes. At the same time, automatic mail forwarding from the first box to the second is configured. And it turns out that all incoming letters are duplicated. You can say - just remove the first box. But it is needed to send mail. There was no such duplication in native Mail. Can you tell me how to set up Spark to avoid duplicates?
