As you can see in the ksdensity documentation, depending n how you use the function, there is nothing abnormal with your result:
From documentation: Generate a mixture of two normal distributions, and plot the estimated inverse cumulative distribution function at a specified set of values:
x = [randn(30,1); 5+randn(30,1)];
yi = linspace(.01,.99,99);
g = ksdensity(x,yi,'function','icdf');
plot(yi,g);
Paste the code you are using in order to provide a good solution to your question.
