If someone knows a few words from your seedphrase, there is a chance they will see some of the other words. So, I think it would be better if you create a new one. Are you opening it in a public place? Opening it in a public place would be even more dangerous, as we know there are many eyes and lenses in public places. I always avoid displaying my seedphrase in public because I feel unsafe doing so. There is a chance that what we do in public will be exposed, and the most obvious reason is cameras. If I were you, I would create a new wallet in a private place, and keep the seedphrase as safe as possible.
If you want to create your wallet, do it at home, create it offline.
This practice will give you safer wallet creation and avoid possible online threats as well as curious eyes and even cameras at public places. If you do bad wallet creation, the wallet backup process later won't improve security of your wallet and your fund. Because if your wallet mnemonic seed is seen by anyone else, directly or indirectly through camera videos, it's no longer your wallet.
