In Offer Caps setting, please pay attention: 
(1) When Offer reached its Caps limitation, our system won’t change Offer status. For example, Offer is currently in Active, after it reached Caps limit, it will remain Active. However, Affiliate’s traffic will be redirected to Backup Offer that you’ve set for the current Offer.
(2) Caps’ recalculated effective time zone is in accordance with the “Timezone” settings which in “Setup > Settings > General Settings”. For example, “Daily Caps”, system will reset Caps at 00:00 midnight based on Network Time zone settings.
