For some reason, when I updated my server from the official Minecraft bedrock server software thing, it gave me the 1.20.13 update, rather than the 1.20.12, which is what it is supposed to be. It does not allow for me or my friends to play on this server anymore.

I have tried to go back to the server software download and download it again, but it simply downloads 1.20.13 again. Please fix this soon.
