Rearrange rows and columns in Deedle

Question

I have a table like

 Month Cluster Year ActualAmount TargetedAmount 
 1     1       2015 100          200            
 1     1       2016 300          400            
 1     1       2017 300          400            
 2     1       2015 500          600            
 2     2       2016 700          800  

and I would like to have the row values of year as columns like

 Month Cluster ActualAmount.2015 ActualAmount.2016 ActualAmount.2017 TargetedAmount.2015 ...
 1     1        100          300          300          200 ...             
 2     1        500            -            -          600 ...
...

I have tried to solve it with pivotTable (see below). It does not get the index right.

#r "nuget: Deedle"

open System
open Deedle

type Record =
    { Month: int
      Cluster: int
      Year: int
      ActualAmount: int
      TargetedAmount: int }

let Records =
    [ { Month = 1
        Cluster = 1
        Year = 2015
        ActualAmount = 100
        TargetedAmount = 200 }
      { Month = 1
        Cluster = 1
        Year = 2016
        ActualAmount = 300
        TargetedAmount = 400 }
      { Month = 1
        Cluster = 1
        Year = 2017
        ActualAmount = 300
        TargetedAmount = 400 }
      { Month = 2
        Cluster = 1
        Year = 2015
        ActualAmount = 500
        TargetedAmount = 600 }
      { Month = 2
        Cluster = 2
        Year = 2016
        ActualAmount = 700
        TargetedAmount = 800 } ]

let df = Frame.ofRecords Records

df.Print()

let pdf = df |> Frame.pivotTable (fun k r -> r.GetAs<int>("Month")) (fun k r -> r.GetAs<int>("Year")) id
    
pdf.Print()

     2015                                       2016                                       2017                                       
1 -> Deedle.Frame`2[System.Int32,System.String] Deedle.Frame`2[System.Int32,System.String] Deedle.Frame`2[System.Int32,System.String] 
2 -> Deedle.Frame`2[System.Int32,System.String] Deedle.Frame`2[System.Int32,System.String] <missing>                                      

Any help is appreciated.
