Arena tournaments listed multiple times

Hello lichess,

after yesterday's blackout of our favorite site, I just noticed that in the advance announcements of the arena tournaments, many dates of one and the same tournament are listed multiple times.

For example, this date five times:
“Chess960 Shield Arena
Sept. 15, 2024, 6:00 p.m.”

I am sure that you will gradually fix all the errors that have occurred.

Thx and all the best.

The tournaments listed multiple times have different IDs for each instance, not sure what people who want to join the tournament in advance should do. Join all of these instances?
