fmincon displays huge unwanted output text

Hi. Does anyone know why fmincon would ignore a 'Display','off' setting in the options? Here is my code:

opt = optimset('MaxFunEvals',200000,'Display','off');
... more code ....
opt = optimset('Algorithm','active-set');
f = @(xx)xfunc(xx,A,b,l,L);
[x2] = fmincon(f,zeros(256,1),[],[],[],[],zeros(256,1),Inf,[],opt);

In the output it still tells me:

Local minimum possible. Constraints satisfied.

fmincon stopped because the predicted change in the objective function
is less than the default value of the function tolerance and constraints 
are satisfied to within the default value of the constraint tolerance.

Active inequalities (to within options.TolCon = 1e-006):
  lower      upper     ineqlin   ineqnonlin
    1                                 
    2                                 
    3                                 
    4   
...

And this goes on up to 256, using up a huge number of lines. I'm pretty sure I've specified the display off correctly using the optimset function. The code itself is minimising f subject to every variable being non-negative, if this is relevant.

Does the second optimset affect the first perhaps?

Thanks for any suggestions.

Yes, the 2nd optimset completely overwrites the first. Do this instead

opt = optimset(opt, 'Algorithm','active-set');

great, thanks. I assumed it could be added to rather than overwritten.
