My activities are being added to two challenges so I'm double dipping. How can I correct that?

Challenge Hound will apply applicable activities to all challenges you've joined and that are active. Many participants enjoy multiple challenges at once and double-dipping is not an issue. 

If you don't want to double dip and would rather do challenges sequentially, then the challenges can be set up to not backfill and then participants will just join challenges in the order that they want to complete them.

If you've joined two and didn't realize they would double-dip, then contact your challenge administrator or Challenge Hound and you can be remove from one of the challenges.
