It seems you all agree that the addresses should be the same, but they are not. I created a new wallet with the same bit39 seed, this time using keepKey derivation path: m/44'/0'/0' but without using a keepkey. Result: the addresses are different.

As hosseinimr93 said, your derivation path must start with 84' for native SegWit (Bech32) addresses. Native SegWit addresses start with bc1q.

Try these derivation paths:
m/84'/0'/0'
or
m/84'/0'/0'/0'

By the way, did you happen to use any step-by-step guides or tutorials while setting up Electrum with your KeepKey hardware device? It can be useful to retrace all your steps to find out what exactly is happening (perhaps you used an additional passphrase, or you chose a different account on your KeepKey device ...)
