Thank you for your patience. I've looked into this case and found that the ordering levels you saw were not correct. Sometimes our system can adjust these levels when your account is brand new or if it has updated information, but we've refreshed your account to better reflect the information at hand.
Keep in mind the limits you have now may not be permanent. They will change dynamically over time based on many factors including, but not limited to, your account activity, transaction history, and payment method use.
You can keep track of your current limits on the verifications page here:

Thank you for using Coinbase.
