Error during run, Radius array is <= 0

I have got this following error while running prodigy on my protein-protein complex
[!] Error when running freesasa:
[!] Error: Radius array is <= 0 for the residue: ILE ,atom: O01
Please Help.

Thank u
Vivek

O01 is not a normal amino acid atom nameā€¦ Either correct it or remove it
