To be eligible for the rich result, a question must have at least one answer – either an acceptedAnswer or a suggestedAnswer . However, questions may not have answers when they are first posted. For questions without answers, set the answerCount property to 0. Questions without answers aren’t eligible for the rich result.

As per the Google’s doc we already set answerCount to 0 for unsolved topics. You should not worry about this alert.
