Android 4.3 Bugs on GS4?

I have the Verizon GS4 and I recently got an update to 4.3, surprisingly.

But I seem to have a few bugs.

1. I keep getting a Knox notification that something tried to bypass security even though there's nothing weird that I've installed. No pirated apps, no 3rd party apks from weird websites, nothing.

2. The animation scale keeps resetting to 1 even though I change it to 0.5.

Is anyone else having these issues on the GS4? Does anyone know how to resolve them?
