Custom CSS snippet permanently changed style

I added a custom css snippet to obsidian to add bullet point relationship lines. I did not like it and now I cannot remove the customization.

INFORMATION:
The first thing I did was toggle the custom css off which did nothing. Then I deleted the snippet and it did nothing. I have tried everything I can think of and need help.

I am using obsidian sync and the css issue pushed to my mobile device.
I deleted all vaults and sync vaults and the problem persists. I also deleted and reinstalled the program. I also tried switching themes. If anyone knows how to fix this problem, I would be very grateful.
