You most likely have multiple accounts you take care of so unless you log off multiple times (yes, you have to do that) PM site might show previous log in.
@PercyQ If you have more then one account try only using the phone associated with the specific account is best or you need to open new web browser window and try again incognito mode /private mode or use the app instead if you haven’t already . Even with all of using same device you should clear app cache when accessing your second account or uninstalling the app and re install each time if you use same device to manage all accounts
