Large formula not returning desired results

Hi Guys

I'm trying to Rank cells V4 from highest to lowest. I have a LARGE formula in place but it doesnt seem to be working out. It does not give me everyone from A4:A50. It also duplicates the figures.

In cell U4 i match V4 and it pulls a name associated with that average but this does'nt seem to work out as well cause it duplicates the names.

I hope i'm making sense here..
