Duplicate Luke Mulcahy profiles

My IMDB credits are on Luke Mulcahy (II). This is because I hadn’t realised I was given a credit on a short film I did ages ago, on Luke Mulcahy (I). I got the director to transfer the credit to Luke Mulcahy (II), and presumed Luke Mulcahy (I) would disappear, but it has not, it exists as a blank actor profile with no credits. How can I resolve this? I don’t want my main page to be Luke Mulcahy (II) when I am the only Luke Mulcahy on IMDB. Would really appreciate any guidance :)
