O365 LastPasswordChangeTimestamp property not updated after user changed his password

In my Office 365 tenant, one of the user changed his password January 5th (I have the proof through an Activity alert I have set sent by Office 365) but the LastPasswordChangeTimestamp  property that I query using PowerShell is still showing the previous date when he changed his password (Sept 24, 2019).

We are using Office 365 alone (our AD is on-premise and fully disconnected).

We have a policy set to have the password expiring after 90 days. The user still have access to his mailbox.

Anybody saw that before? How to fix?

When you say you query it using PowerShell, you mean you're connecting to the msonline module first then running something like

Get-MsolUser -UserPrincipalName joeblow@yourdomain.com | Select-Object LastPasswordChangeTimestamp

absolutely. I see all properties except that the value is set to Sept 24 instead of being Jan. 5.
