Update future tournament - cog has gone???

I've just created a tournament for next Monday and need to move it to Tuesday - I though there was a "cog" I could click on to make changes - I don't see this any more ??

See lichess.org/swiss/EIuxQ4LO

As tournament creator how can I make changes ? (or even delete it and raise another one)

Help please !

thx,Keith

Have you tried Joining the Tournament first ?
