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.

Some friends here have given you references for storing your seedphrase safely, so please pay attention. In addition from me, I recommend storing it in a paper wallet, writing it down on paper (make sure there are no mistakes), then storing it in a safe-deposit box or steel vault (if possible). So, I think that is a safe way, even if an unexpected disaster occurs, such as a fire or flood, it will still be safe. Cmiiw.
