iCloud.com Calendar all day events spam across 2 days

Since a recent update to the iCloud.com website, I've noticed all day calendar events are spanning across two days. When I look at the same events on my iPhone or MacBook there's no problem, events only appear on the 1 day.

I've tried different web browsers, I've made sure my time zone settings are correct. If I change the event from all day to specific hours during the day, it works fine, it's only affecting all day events.

Haven't been able to find a solution, any suggestions welcome!!
