Why this page is separate from the download. If the hash sat next to the download button, anyone who could replace the file could edit the hash beside it, and the two would agree perfectly while proving nothing. This check is worth most when the file reached you some other way — by email, on a USB stick, from a friend — and you came here yourself to read the hash.

If the hashes do not match, stop. Do not enter a real seed phrase into that file. It may have been corrupted in transit or deliberately modified. Download a fresh copy from bip39toolbox.com and check it again before trusting it with anything of value.
