I set mine up using that guide and followed the instructions to a T. It's giving me addresses that start with a 3. If I had to guess in your case, perhaps a step could have been missed or not done exactly as shown. I think it's the first several steps of that guide that are responsible for getting the "3" addresses, up to and including changing the 44 to 49. Also, the guide is missing one step - after the wallet is setup, you have to go into Tools-Preferences, and on the Fees tab, check Edit Fees Manually.

To update my last post, my transfer was successful. The transaction (tx) size was 136 bytes instead of the usual 226, resulting in that much smaller of a miners fee. This was due to using a segwit address, and something else I just figured out: when u send all of the btc in ur address, leaving nothing behind, the transaction size is smaller so the fee is smaller.
When we send to our bitpay cards, we can't send the exact amount in our address, because bitpay makes us give them a figure up front. That means that when we send, all of the btc is taken out of our address (this is just how btc works), and the remaining amount we aren't sending to bitpay (or whoever) goes back into our wallet
in a new address, as change. So there are two "output addresses" instead of one - bitpay's address and the newly created address where ur "change" goes back in ur wallet.
When we send to coinbase/gdax, we can send
all of the btc in our address, so there's only one output address in the xfer - the one for coinbase. There's no "change" address. When this is the case, for normal btc txs the tx size will be ~192 bytes instead of 226 bytes. When using a segwit address, as far as I can tell, for one output address txs it will be 136 bytes and for two output address txs it will be 166 bytes.
Since miner fees are based upon how many bytes each tx is, the less amount of bytes, the cheaper the miners fee.
To summarize, compared to using the blockchain wallet in conjunction with the bitpay card, by using electrum with cb/gdax, we:
1. have cheaper miners fees due to using segwit addresses
2. have even cheaper miners fees due to being able to send the full amount in our address
3. don't have to pay bitpay's admin fee
