Adding Repeating Weekly Events adds wrong day

I have installed 14.0.0-RC2. When adding an event to a Space, I try to include an event that begins on 29 January 2025 at 18:00 and ends on 29 January 2025 at 19:00.

Then I add a repeating event for every Wednesday ending on 5 Feb 2025.

But this is what shows up on the Space calendar
