Set-up failed: received 22 seeds - should be 24?

Model One. Trying to set it up.
Facing the following issues:
Backup failed twice. A note tells me to wipe the Trezor and do the setup process again.
If I understand it correctly I need to have all the seeds to be able to do that.
I have received 22 seeds. Shouldn’t it be 24???
I haven’t wiped the Trezor yet since I am afraid it will not work if I don’t have all the seeds.
Any comments?

If you don’t have any coin in your wallet and hidden wallet , wipe the Trezor and reset it again .
Until you can restore your wallet . don’t use it.
This is what to do :

  1. set your trezor , write 24 word down
  2. get into your standard wallet , copy the btc first receive adress to a txt file
  3. wipe it and restore your wallet use advanced recovery . This may take you 15-20 minutes
  4. When your trezor is restored , get into your standard wallet copy the btc first receive adress to that txt file. If the two adresses are the same . You have your 24 words right to do next
  5. Write a few more received 24 seeds . Put them into more than two houses .
  6. Open your Passphrase Option. Write down the phrase more than one copy and put them into a different room in the house where you put your received 24 seeds.

Then you can use your wallet !
