“Last updated” is changing

I first noticed that the notes I had just entered were not sorted at the top, and then I noticed that the “Last updated” date for those notes changed to tomorrow's date.

After restarting Capacities, the “Last updated” date is normal.

Please compare the two screenshots I uploaded, they have the same “Created at” date and time.

I'm not sure if it's due to the internet, but I have a feeling that the “Last updated” date is not my computer's date.
