Why can't I delete the entire downloaded samsung theme/icon from from Note 8?

[Android Central Question]

I tried to delete a theme/icon from Samsung that I previously downloaded. Most of the theme deleted but some of the apps and the home page apps/icons won't change to new theme or icon set. I tried several times to download a new theme or icon but the old theme remains along with the new one I downloaded. It's like I have a combination of old and new theme/icon.

I can't even find the theme that I want to get id of cause I deleted it.

Any help would be great!
