Seafile Client 6.0.0 Sync Notification Does Not Shows Out on Window XP

Hi, i couldn’t find the answer in the forum, therefore i opened this new topic.
I’m using seafile client 6.0.0, i noticed that "Notification when Libraries are synchronized did not shows out on Windows XP even i already checked the box for “Notify when libraries are synchronized” under Basic tab in the settings.

Please guide me on this. Any helps from you all is highly appreciated.
