IB - Double charge for Data Feed

Ahh I found it! Here's how I got to it:
1. Logged into IB's website
2. Clicked the three-horizontal-line thing in the upper-left-hand corner
3. Click "Reports"
4. Click "Statements"
5. Clicked the gear-button next to "Statements Delivery" on the right-hand-side
6. Clicked the gear-button next to the "Notification Defaults"
7. Selected "Email with Attachment" instead of just "Email" from the dropdowns.

Thanks @HobbyTrading
