Kraken fees higher than advertised?

I've just pulled out this month's DCA from Kraken to my Trezor and noticed that instead of the 0.0002 fee advertised by Kraken, my Trezor is showing a fee of 0.001

Am I missing something? Looking back on previous transactions I can see that I've sometimes been charged 0.0002 and other times 0.001

My Kraken app is still showing the completed transaction fee at 0.0002
