Do you have a subscription directly with Paramount+? "CBS Interactive" is usually how the subscription to Paramount+ shows up on your statement when you have one through Roku and it's possible to have a subscription both through Roku and directly with Paramount+. I don't know how subscriptions are displayed in your Roku account, so it's possible that if it's shown as Paramount+ in your Roku account at https://my.roku.com it's the same one that's shown on your statement as "CBS Interactive through Roku".
