There is a folder in my photo gallery that won't delete can anyone help?

I go on to my photo album/gallery and there is a album called angel. I can't remember creating it and I don't know why it would be there in the first place. It says it has no photos in it and usually on my phone (LGK8 2017) when a photo album has no photos in it automatically deletes its self, but this isn't deleting even when I try do do it. Please can you help me find a way to delete this folder. Thanks.
