DAI showing as unknown token

Since I updated both suite and trezor firmware yesterday, DAI is showing as unknown token on the trezor Hardware when I try to send it. It also shows an exaggerated figure such as 40000000 if I try to send $400 worth of DAI. Also it says WEI UNKN ‘send 4000000000 UNKN WEI’

What should I do?

which DAI are you transacting? what is the contract address?
