Workflow email notification not coming through correctly

 My workflow is that when someone sets an Opportunity to Closed/Won it will notify me by email. My workflow Action looks like this:

Subject: %%%[<Owner>]%%% has Won an Opportunity with %%%[<AccountName>]%%%

Message Body: Win Details:

Account Name: %%%[<AccountName>]%%%

Opportunity Name: %%%[<OpportunityName>]%%%

Owner: %%%[<Owner>]%%%

Campaign: %%%[<SourceCampaign>]%%%

Revenue: $%%%[<Revenue>]%%%

Close Date: %%%[<CloseDate>]%%%

Cloud Overlay Specialist: %%%[<IndexedPick1>]%%%

Public Sector Overlay Specialist: %%%[<IndexedPick2>]%%%

Business Development Rep: %%%[<IndexedShortText1>]%%%

Inside Sales: %%%[<stInside_Sales_Rep_ITAG>]%%%

Field Sales: %%%[<stField_Sales_Rep_ITAG>]%%%

It works and everything comes through to my email...except that it looks like this: 

Win Details:

Account Name: Denovo Ventures, LLC

Opportunity Name: Test Test
