bulk folder in Mac mail Catalina

My email provider is ATT. I don't know how to set up rules. Will have to learn. However, I dragged the two bulk folders up far enough so they resemble junk folder and the crazy thing is nothing is going to my junk folder but to these two bulk folders for my two att emails. Ive never had a bulk folder before in my Mac mail 13.4. I have read there's no way to delete them so Im going to have to deal with them. they are NOT on my webmail with ATT. the folder there is called SPAM. Thanks for your reply. They were added when I lost my classic look and had to delete, re-add my email accounts. Funny thing is my third email that I don't use much with apple doesn't have a bulk folder. So it must be my att who put this on there as a spam, junk folder.
