Getting same values for first column of kernel-PCA

So I have a dataset of 36 features x 57 observations

I'm using this file-exchange code for kernel-PCA.

For some reason, I'm getting the exact same value in the first principle component. Just a line of code:

projected_data = kernelpca_tutorial(handles.all_data, 3);

Anyone else run into this issue?
