<entry lang="en" key="HIDDEN_CREDS_SAME_AS_OUTER">The Hidden volume can't have the same password, PIM and keyfiles as the Outer volume</entry>
to
<entry lang="fi" key="HIDDEN_CREDS_SAME_AS_OUTER">Piilotetun taltion salasana, PIM ja avaintiedostot eivät voi olla samat kuin ulomman taltion</entry>

also

<entry lang="en" key="SYSENC_BITLOCKER_CONFLICT">VeraCrypt does not support encrypting a system drive that is already encrypted by BitLocker.</entry>
to
<entry lang="fi" key="SYSENC_BITLOCKER_CONFLICT">VeraCrypt ei tue järjestelmäaseman salaamista kun se on salattu BitLockerilla.</entry>

Please check first I would like to avoid (same) words translated differently (however the finnish translation is horrible anyways) I tried to make it compatible with the previous translations

I have pushed your transaltion with small modification to first sentence: https://sourceforge.net/p/veracrypt/code/ci/e87bd79501f93607af41c75747e838dea53f06f1/

Thank you again.
