Outlook 2013 White list messages disappear from inbox

[size=12pt]Just started using Avast Premier (19 Oct 2015). When I select a message in Outlook 2013 inbox followed by clicking the whitelist icon my message goes AWOL.
The safe method for me to use at the moment is to delve deep, [Settings]>[Active Protection]>[Antispam] select customise>[Whitelist] add contact. This is tiresome and longwinded!
Is there a solution to this issue?
