Why import data tool replaces logical values with NaN?

Hi,

I have a matrix on MATLAB and want to save the matrix as ".dat" file, I achieved this but when I import these data to MATLAB it replaces some cells with NaN. But these cells are not including any string etc. I just can not understand where is the problem.

Thanks

Rafet
