Sent ETH transaction disappeared from Trezor T transactions

hi, i have sent several ETH from my Trezor T to an exchange. The transaction is still pending nearly 2 hours later. What concerns me is that the pending transaction has disappeared from the latest sent transaction list in Trezor T. There is no mention of the ETH i sent or in the current balance on Trezor T.

Strangely I have a another wallet which allows me to ‘view only’ my Trezor T balances and transactions… the ETH transaction is recorded in this other wallet yet not displaying in Trezor T.
