Word document info page contradictions

Hi all , First time here and I am looking for some advice since I cant get my head around it. I have also asked google but still cant get the right answers.

I have been sent a screenshot of the info page of a Word document. The document is supposed to be typed teams meeting minutes that took place between 13:00 and 13:30 on the 20th of May 2025. Properties on the screenshot show the below info:

Size : Not saved yet

pages :2

words: 285

total editing time : 45 minutes

last modified : 12/01/2026 14:55

created: 20/05/2025 13:00

Is anyone able to explain how a file can have a “last modified” date but size can show “not saved yet”. The word document would be generated inside corporate account if that makes it more possible?
