How to change profile banner and delete listed dolls?

Hi guys! I'm coming back to this site after quite a while, so I've been updating my info. Some of the dolls on my banner and listed under My Dolls have been sold and I no longer have them, so I'd like to remove those but I can't figure out how. On my profile I couldn't find anything to click on to change the banner, and I couldn't find any way to delete the doll entries I've made. Any advice?

Omg... So I went back to my profile to look around more, and now suddenly there's a third option there to change the cover photo. =3= So I checked my doll entries again too, and now there's an option to "Manage" the entry next to the Report button. I don't know why those weren't there a minute ago but I guess my problem is solved now. lol
