Can't Edit Styles Fully - V2 and Random remain

[JohnFromGWN]

Unlike most users, I only use my only styles. I build in my Lora and prompts and preview images.
I just edited sdxl_styles_fooocus.json and sorted_styles.json and have two annoying issues. I deleted all other style jsons and sample images.

But I have two annoying issues:

1. Even though they don't appears in my modified json files, i still get unwanted styles: Fooocus_V2 and Random Style. Can I get rid of these. If so which files?
2. If Fooocus_V2 does not have a preview image in the Samples folder, I get a fatal error. Again, how do i deal with this?

I don't want either of the 2 styles above and I don't want sample images other than those for my own custom styles.

EDIT: the file that contains this is sdxl_styles.py
this worked for me
style_keys = list(styles.keys())
random_style_name = ''
legal_style_names = style_keys
