Recovering multi sig seed phrase

Hi everyone,
I just set up my Trezor Suite 5 and recovered my seed from a multi sig on my BlueWallet. This wallet had 3 vault keys, that is 36 words in total but I only needed to use the first 12 to set up trezor suite 5. Have I generated a new private key which is now 12 words instead of 36? If so when I transfer btc from BlueWallet to trezor will I consolidate utxo’s
Long question sorry.
Thanks anyone who can shed light
Donald
