I don't think that the problem lie in WPP. WPP doesn't interact with scheduled install or AU Agent Policy.
In the WPP interface, does the status of the update is "Not installed" or "Downloaded" ?
- Can you try with an oldest release (v1.2.1306.16 for example) ?

Does this occur on one computer or several ?
