Repeated old buyer request

[ashiq133]

Hello everyone, 10 days ago i achieved level 1 badge . After that some wired staff is happening in buyer request section. I started to see very old buyer request even more than 1 month older buyer request. I tried removing . But again they come back once or twice. I rarely see any new buyer request now a days. Is it a fiverr bug or something else ? Really tensed about this. Your thoughts and suggestion would be really helpful.
