Why is sscanf skipping 2 columns on second line?

Hi!
I have a text file that has four numeric values on every other line and a date on every other. Sscanf auotmatically skips the date lines, just as I want it to. Howver, when it starts reading the numeric lines, on the second line it only grabs values from the first two columns(four exist altogether). All the other lines are treated correctly. What might be going on? The source file in question is attached to this message.
THanks a lot in advance!
fid2=fopen('allMeasurements.txt','at');
R=0;
D= [9 11 12];
for i = D;
s1=num2str(i);%Next lines creat filename
if i<10;
s0='0';
s1=strcat(s0,s1);
end
s0='000';
s=strcat(s0,s1,'.txt');
sd='data';
s=strcat(sd,s);
fid=fopen(s, 'rt');
while fgetl(fid)~=-1;
R=R+1;
A = sscanf(tline,'%f', [1,4]);%The 4 columns are stored in A
fprintf(fid2,'%f %f\n',B);
end
fclose(fid);
end
fclose(fid2);

and try

cac = textscan( fid, '%*s\n%f%f%f%f', 'Delimiter','\t', 'CollectOutput',true );
fclose( fid );
