Kraken charges greater than marketed?

I've simply pulled out this month's DCA from Kraken to my Trezor and seen that as a substitute of the 0.0002 charge marketed by Kraken, my Trezor is displaying a charge of 0.001

Am I lacking one thing? Wanting again on earlier transactions I can see that I've generally been charged 0.0002 and different instances 0.001

My Kraken app continues to be displaying the finished transaction charge at 0.0002
