Indicator not plotting!

Hey guys, I wrote a simple indicator that plots "Sections" on the chart. i checked that the buffer arrays are filled correctly, but it is still not plotting the lines.

I tried everything, and now simplified the code as simple as possible, still not plotting:

#property indicator_chart_window
#property indicator_buffers 5
#property indicator_plots   5

//--- plot TF1
#property indicator_label1  "1"
#property indicator_type1   DRAW_SECTION
#property indicator_color1  clrRed
#property indicator_style1  STYLE_SOLID
#property indicator_width1  2
//--- plot TF2
#property indicator_label2  "2"
#property indicator_type2   DRAW_SECTION
#property indicator_color2  clrRed
#property indicator_style2  STYLE_SOLID
#property indicator_width2  2
//--- plot TF3
#property indicator_label3  "3"
#property indicator_type3   DRAW_SECTION
#property indicator_color3  clrRed
#property indicator_style3  STYLE_SOLID
#property indicator_width3  2
//--- plot TF4
#property indicator_label4  "4"
#property indicator_type4   DRAW_SECTION
#property indicator_color4  clrRed
#property indicator_style4  STYLE_SOLID
#property indicator_width4  2
//--- plot TF5
#property indicator_label5  "5"
#property indicator_type5   DRAW_SECTION
#property indicator_color5  clrRed
#property indicator_style5  STYLE_SOLID
#property indicator_width5  2

//--- input parameters
enum ENUM_TF {DISABLED, M1, M2, M3, M4, M5, M6, M10, M12, M15, M20, M30, H1, H2, H3, H4, H6, H8, H12, D1, W1, MN}; // Enumeration for Timeframes
input group "|||| TIMEFRAMES || - Current Timeframe excl.";
input ENUM_TF  TF1=M5; // Timeframe 1
input color    TF1color=clrAqua; // Timeframe 1 line color
input ENUM_TF  TF2=M15; // Timeframe 2
input color    TF2color=clrGreenYellow; // Timeframe 2 line color
input ENUM_TF  TF3=M30; // Timeframe 3
input color    TF3color=clrYellow; // Timeframe 3 line color
input ENUM_TF  TF4=H1; // Timeframe 4
input color    TF4color=clrDeepSkyBlue; // Timeframe 4 line color
input ENUM_TF  TF5=H4; // Timeframe 5
input color    TF5color=clrGoldenrod; // Timeframe 5 line color
input group "|||| GENERAL SETTINGS ||";
input int      Lookback=1000; // No. of Bars to illustrate

//--- indicator buffers
double         TF1Buffer[];
double         TF2Buffer[];
double         TF3Buffer[];
double         TF4Buffer[];
double         TF5Buffer[];


// HERE I AM CALCULATING THE VALUES AND WRITING THEM TO THE BUFFERS

   SetIndexBuffer(2,TF3Buffer,INDICATOR_DATA);
   SetIndexBuffer(3,TF4Buffer,INDICATOR_DATA);
   SetIndexBuffer(4,TF5Buffer,INDICATOR_DATA);

//--- Initialize the buffers

   ArrayInitialize(TF4Buffer, EMPTY_VALUE);
   ArrayInitialize(TF5Buffer, EMPTY_VALUE);

   return(INIT_SUCCEEDED);
}

{

   ProcessTimeframe(TF1, TF1Buffer, rates_total);
   ProcessTimeframe(TF2, TF2Buffer, rates_total);
   ProcessTimeframe(TF3, TF3Buffer, rates_total);
   ProcessTimeframe(TF4, TF4Buffer, rates_total);
   ProcessTimeframe(TF5, TF5Buffer, rates_total);

   return(rates_total);
}
//+------------------------------------------------------------------+

My BufferArrays are filled as follows:

Any advise why it is still not plotting?
