RSRP-287695: VB.NET: Wrong item selected automatically

Suppose you have an ENUM:

Public Class ReportViewer
  Public Enum ReportType
        XML
        CSV
        TIFF
        PDF
        WEB
        WebArchive
        XLS
        RPT
    End Enum
End Class

Now let's say you are trying to call a method with the signature:

Public Function Generate(ByVal outputPath As String,
                        Optional ByVal reportType As ReportViewer.ReportType = ReportViewer.ReportType.PDF) As String
...
End Function

So you type:

SomeObject.Generate(somePath, reportType:

As soon as you typed the ":" R# makes a replacement:

SomeObject.Generate(path, ReportViewer.ReportType.CSV:

This isn't what I wanted. I wanted to type:

SomeObject.Generate(path, reportType:=ReportViewer.ReportType.PDF)

This is very annoying when it types the wrong thing.
