Undefined Index

Having some issues with indexes. Would appreciate any help troubleshooting.

I'm running a pick-the-winner with tie-break league. When a new user creates an account, the first time they go the League Summary page they the error below. There's no rank, points aren't 0, and high and low weeks labeled "Week()" The only way I get rid of this issue is to clear the cache. How can I resolve this and not have to clear the cache each time? The only thing I've done is deleted a few user accounts. Thanks!
