Draft emails getting a bit annoying

I don't remember when it started but it's been several months. When composing an email the system constantly saves a draft in the Trash>Recover Deleted Items folder. I sometimes go back & recover deleted emails, the draft clutter from composing an email & say taking a phone call, or not finishing it right away will cause multiple drafts to be saved in the Recovered Deleted Items folder. Maybe if we had a search bar feature it wouldn't be so annoying.

Is there any way to change it? I thought maybe I had changed a setting to save frequently but I can't find anything in the settings.
