It is just that the actual geometry of the plate capacitor is such that these fields add up in the slab region and vanish outside which explains the result you find with Gauss'' law. Remember that Gauss'' law tells you the total electric field and not the one only due to the charge you are surrounding. That is because, when using Gauss'' law, you ...
