[D] Issue with arxiv - abstract not matching pdf/html [D]

Hi, I was reading the openRLHF paper: https://arxiv.org/pdf/2501.03262v4 , but when I click the abstract page: https://arxiv.org/abs/2501.03262v4 , it shows "REINFORCE++". Note that https://arxiv.org/html/2501.03262v4 still shows the correct openRLHF paper. I believe Arxiv is having some incorrect symlinks?

Is there anyone working at arxiv here who would like to look into this?
