Hi there,
Thanks for your report. Twitch Prime rewards can only be claimed once per account. We recommend making sure that you have your accounts linked correctly to ensure that you can receive next month's rewards.
You can verify if you have successfully linked your Twitch Prime account to your current Bungie.net profile by navigating to Settings > Accounts & Linking, and navigating down to the Authorized Applications section.
