Indesign Spell Check Issues

Even though the "case sensitive" box is unchecked, the indesign spellcheck still flags lowercase titles, etc that were changed via the "change case" feature. Even thought the titles appear in all caps, they were typed in lowercase and changed later but are still flagged as lowercase words. 

Is there a different way to omit case from the spell check? Also, in regard to placeholder text (latin) is there a way for Indesign to ignore this?
