Spell Check Not Working on some Styles

Hi everyone,

My spell check is being very weird. It is working in some sections of my document, but in others it's not. Basically I misspelled words on purpose and I get no red underline and it just ignores it in the spell check. Quite frightening. Is there some way that I maybe selected "No language" on accident for this style, or is my document corrupted?

Thanks for any help,

Paulette
