Accidentally bridged Phala (ERC20) to an Kusama Ledger Account

I have an issue because I accidentally bridged Phala (ERC20) to an Kusama Ledger Account. Instead of choosing the Test Account I prepared I set the destination address by clicking on the “MY ADDRESS” button to the Kusama Ledger Account. Now I can see the correct balance of the transferred tokens in the Phala App but cannot sign any transactions and get the following error message:

On the site i can only transfer to the address of Kusama Ledger Account but do not see it in the account tab.

Are these funds locked now forever? Or is there a way now or maybe at a later stage to tansfer the KPHA.

Resolved - can be closed
