If so, you are importing a wrong seed phrase or the address you are looking for is beyond the gap limit.
Go to "Addresses" tab and check whether you see the address in question or not.
If you don't see the address and you are sure that you have imported a correct seed phrase, you can try generating more addresses using the command below in "console" tab.
Note: If you don't see any of "Addresses" or "Console" tabs, you can make them available by clicking on "View" button at top of the window.
