Problem With If else statement

VB

If else statements are really not the issue but in my case I am using regular expressions and match collection to add matches found to a listview else write values to a local database but for some reason the else statement is not acting as it should and writes all values to my local database?.. any ideas are appreciated as to why its writing all but ignoring the else statement.

Dim matches1 As MatchCollection = Engine.CLAM_VIRUS_NAME.Matches(VReader)
    For Each Newmatch As Match In matches1
        For Each s As String In Subtract__List
            Dim Split_S() As String = Split(s, "|")
            Dim FS As String = Split_S(0)
            Dim OFP As String = Split_S(1)
            If M.Success = True AndAlso s.Contains(File_Name.Value) = True Then
                Add_Listview_Records(OFP, VN.Value, File_Name.Value, FS)
                For upIndex = ListView1.Items.Count - 1 To 1 Step -1
                    Dim upItem = ListView1.Items(upIndex)
                    For downIndex = 0 To upIndex - 1 Step 1
                        Dim downItem = ListView1.Items(downIndex)
                        If AreEquivalent(upItem, downItem) Then
                            ListView1.Items.Remove(upItem)
                            Exit For
                        End If
                    Next
                Next
            Else
                Engine.Insert_Access_Records(FS)
            End If
        Next
        Label8.Text = CStr(ListView1.Items.Count)
       VN = VN.NextMatch
        File_Name = File_Name.NextMatch
    Next Newmatch

I Know it must have something todo with the logic of the code but however I try it will still write all values instead of only the matches that are not found.

thank you in advance!
