Using Seed to Restore an Account

Hi, I’m trying to restore my password on polkadot.js.org in order to unbound my funds from a vote, and the process doesnt seem to work.
The step outlined in the wiki:

Using an Existing Mnemonic Seed to Restore an Account

does match the current UI, since I cannot restore the account with the existing seed.
My .json file of the account was not encrypted when I created the account, so trying to use it to restore the account also doesn’t work, since that step also requires a password (supposedly the one which encrypted the file)
