White background on highlight when using highlight symbols under cursor under cursor

[MadFisa]

When using the code in https://github.com/neovim/nvim-lspconfig/wiki/UI-customization#highlight-symbol-under-cursor for highlighting all the occurances of a symbol using lsp, the highlight appears as white, making the text unreadable.

I dont know much about colorshemes, but my guess is that problem is not implementing group = 'lsp_document_highlight' in the colorscheme. Let me know if you need any more information.
Love the work you have done btw.
