Nice catch Andre!!!
np.set_printoptions(suppress=True) solved it.

The behaviour you're describing sounds like a matter of pretty-printing. Numpy uses a shortened format for printing numeric values by default. When you convert to a list, you leave numpy behind and you get the native python behaviour. If you want to control how this pretty-printing happens in numpy, take a close look at
Now, I still don't see how taking a trivial view of your array would affect this printing, but I believe your values themselves are identical (i.e. correct) in both cases, and they are only displayed differently. If you were to do further computations with your arrays, the results would be the same.
