Trash icon missing in iOS 16

Thanks. The problem is this: For most of my emails on my iphone (and for all my emails on my macbook and imac, which of course are all the same), left swiping firmly deletes the email, and swiping gently gives the delete option. But for some, only with the phone, the left swipe options instead are More, Unread, and Archive. I don't want that, and didn't have it before. I just want delete. I realize that, as you pointed out, by tapping More, I can get to another screen which allows deleting. I don't want that. I want just the delete option. How did this happen, and how do I get back to the situation on my phone where left swipe always yields delete? I appreciate your help. Pete.
