Hi!
I was confused about this but I’ve found it’s just a bug (not critical).
If you open a document in the Dashboard, and go back, you will see “Just now“ (or any minutes after going back) in the “Last update” column for that document. This is wrong since there is no change at all, just opened the document and go back.
If you refresh the window, everything is fine, so that last update change is not really saved in the database, but it is in the client I guess.
The screenshot is self-explanatory, since last update documents should be at the top of the list. I just opened those 3 documents and go back to the list without refreshing.
