FullName not getting detected properly from JAPE (NLP)

I am new in Gate develement and now I am trying to extract the fullName from JAPE rules in GATE developement. It is extracting - Namrata shahade Shahade Namrata Namrata N Shahade Namrata N. Shahade all these types of name, from the rule Phase:secondpass Input: FirstName LastName Token Options: control = appelt

 Rule: FullName
 Priority: 20
 (
    ({FirstName}({Token.kind=="word"})?({Token.string=="."})?{LastName}) |
    ({LastName}({Token.kind=="word"})?{FirstName})

 ):label2
 -->
 :label2.FullName = {rule= "FullName" }

But the problem from rule is also detected mail name ie;namrata.Shahade@gmail.com, it is detecting namrata.shahade which is not correct. Please help to correct it. Thank you in advance.
