What's Wrong?

I created a few sessions in sequence. As shown in the image, I created three sessions under the same event, but they appear to be listed in the wrong order. The third item in the list is actually the most recent one.
Also, they are shown with the same time, even though they were not created at the same time.

What Should Happen?

The sessions should be displayed in the correct chronological order, with the most recently created session appearing first or according to the intended sorting logic. Each session should also show its actual creation timestamp, so different sessions created at different times are not marked with the same time.

Steps to Reproduce

1. Open the event page or screen where sessions are listed.
2. Create three sessions in sequence under the same event.
3. Return to the sessions list after all three sessions are created.
4. Check the order in which the sessions are displayed.
5. Check the timestamp shown for each session.
