Good evening Arnau,
Awesome! I am glad you were able to solve the UTC issue!
I still don’t know if it’s problem of WPML (that i deactivated before), i’ll see when i’ll activate again next week. Now when i go to calendar page:

I absolutely believe you and I would love to be able to reproduce this on my end.
Unfortunately, wether I am using the arrows or not, I am unable to reproduce the issue for now.
Would you mind telling me which browser you are using (and which version)?
Additionally, could you try with a different browser and tell me if the issue persists on your end ?
Best regards,
Geoff B.
