I don’t understand the “(sic)” in the title. Everything seems to be grammatically correct, including spelling. What did I miss?

Hi, Zuben... 'sic' doesn't necessarily mean there is a grammatical error; e.g.

 /sik; Eng. sɪk/ Show Spelled Pronunciation [seek; Eng. sik] Show IPA

–adverb Latin.

so; thus: usually written parenthetically to denote that a word, phrase, passage, etc., that may appear strange or incorrect has been written intentionally or has been quoted verbatim: He signed his name as e. e. cummings (sic).
