On Enterprise Portal, Org units are apprearing Twice.

Dear Experts,

I couldn't find any previous thread talking about this issue I am facing so posting it as a new thread. Please help and forgive if this has been discussed before also.

On Enterprise portal we are seeing repeated Org. units( duplicated) while only one org. unit has been maintained for each of them. What should we do to rectify this error?

Please advice.

Thanks and regards,
