Restoring deleted users and Questions & Answers Counter

I currently, deleted two users from my site, including a contributor who Asked and Answer some questions. What I notice is that, the questions and answers are there but the User DP in anspress style first 2 letters Avatar is still there. is there anyway to restore this user to continue using with his old profile. There are also active users who have some repu. but it shows 0 Answers or 0 Questions in counter.  Below image as reference to Counter.
