It's a verb tense error related to the misuse of the past participle form of the verb "mislead". The correct past participle is "misled", not "mislead".
People might make this error because "lead" and "read" in their present tenses change to "led" and "read" for both their past and past participle forms, respectively, which can be confusing. The similarity in sound between "mislead" (pronounced "mis-leed") and "misled" (pronounced "miz-led") might also contribute to the mistake.
The correct past participle form of "mislead" is "misled". Therefore, the correct phrase is "had misled".
