write output to .dat file yielding repeated values

Hello Matlabers,

I'm trying to write my output to a dat file but it apears not all the values are entered. I want the .dat file to look like this image below

Instead my .dat file looks like.

Here is my code:

clear
clc

I = 1; % counter for colums of the dat file

% variables needed to load the file that contains my Values.
nu= 50;
ps=1;

for col=[10,30,50,70] % instead of names i used Numbers because it reads 
    % character of my string istead of takeing the whole name.
    figure_Col(I,1) = col; 
   
    % I load the values to be entered in the table below. each
    %  varaible contains a single value
    load(['CPU_nu_',int2str(nu),'_', int2str( ps),'.mat'],'E_NeNMF_R', 'M_NeNMF_R','E_NeNMF_V','M_NeNMF_V','E_AS_V','M_AS_V','E_AS_R','M_AS_R');
   
    % I try to assign the values to the corresponding cells of the table. 
    % but i guess im doing it wrongly.
    figure_Col(I,2) = E_NeNMF_R;
    figure_Col(I,3) = M_NeNMF_R;
    
    figure_Col(I,5) = E_NeNMF_V;
    figure_Col(I,6) = M_NeNMF_V;

    figure_Col(I,8) = E_AS_R;
    figure_Col(I,9) = M_AS_R;
      
    figure_Col(I,11) = E_AS_V;
    figure_Col(I,12) = M_AS_V;
    
    I=I+1;
    
end
hdrs = {'Algorithm','E-step','M-step', 
    };

namedatfile= [int2str(nu) '_nu_' int2str(ps) '_pass.dat'];
fname = namedatfile;
txt=sprintf('%s\t',hdrs{:});
txt(end)='';
dlmwrite(fname,txt,'');
dlmwrite(fname,figure_Col,'-append','delimiter','\t');

Any help is appreciated.
