Ok... then on the iPad, in the settings for your card, you will need to change the setting to not have RAW files be downloaded (Tap the Settings gear > Eye-Fi Card Settings > [your Eye-Fi card] > Receive Media > Set RAW Photos to OFF).
Whether or not you should return the Pro card is up to you. The Pro card has two features the others don't include but can be added for a fee, and one feature that the others don't have at all. The two features not included with the other cards are the WiFi geotagging and 1 year of hotspot access. The feature not possible on the other cards is RAW upload. If you don't care about any of these features, then it might be worthwhile to return the Pro card and go with an 8GB Mobile card instead. But if you think you might use the geotagging or RAW upload features, or will definitely use the Hotspot feature over the next year, then you may want to keep the card you have.
