It's because the FISC (the "F" is for foreign) is not allowed to spy on Americans. They needed someone in Trump's campaign to wash the spying they were already doing illegally, way before Trump was elected. They needed Carter Page to get to the "two hops" to get to Trump. Carter Page was literally an employee of the CIA (and possibly the FBI as well) and that information was not disclosed, so they hid it, fearing that there's no way a judge would grant their warrant if it was included in the application.
