No Member-Reported Content Problem

Hi friends, i have free annoying problem. iv’e a group and there are about 210 reported posts by members when i click on the reported content i found nothing
i thinks maybe it is old posts or something the i can’t reach or the member who posted maybe his/her account disabled or unavailable i don’t know WTF these posts not showing to me to deal with them
anyone faced this problem and solved it ?
