Mispelled words are not highlighted on Vim 8.2

I enabled `:set spell spelllang=en_us` on a file with obvious misspelt words. The `deus` colorscheme didn't show it, however, when I switched to `:colorscheme default` Vim 8.2 was able to then highlight the misspelt words. Switching back to `:colorscheme deus` those highlights disappeared.

Is it possible to set the `deus` colorscheme to highlight, or underline the misspelt words?
