Cant update my server seed?

[Awsome]

So on my minehut server ive decided to reset it since I had a really fun seed I wanted to play, I got the seed, and then I tried to put it in to update the seed, as I put the seed in I clicked update, except it wasn't allowing me to click the update button. Its like they removed the option to click that update button. Does anyone know a fix to this or some other way to change the seed?

If you install Multiverse onto your Minehut server you should be able to do /mv create <name> <seed> but I'm not to sure what's wrong with the file manager for you're case.
