Excel time difference between dates jumping with day change

Question

I am trying to calculate the time elapsed in a list of dates spanning 3 days.

When the date changes from 10/1/2021 to 10/2/2021 my time difference jumps up +30 days!!!

Here is the screenshot:

Does anyone know how to solve this?

I would like for line 454 to read 0:7:22:02.841.

Ultimately what I am trying to do is to use the the elapsed time as my X axis.

Here is the link for the sample files:

Thank you very much.
