You need to reduce the rank of your data by one. This can happen by several reasons, data recorded with common reference and re-referenced to average, gel bridging between electrodes, too low filter setting (low pass). Set the pca option to 32 before Ic analysis to get 32 ic:s instead.

I collected some data using Biosemi system (32 channels) and after doing pre-processing steps (resampling, filtering, re-referencing), I epoched the data and applied ICA.
My problem is that, I'm getting two similar components in my ICA results (IC3 and IC4).
I uploaded related images here:
Could you please help me with this?
