Why does it show two Jetpack Versions? Which one is the actual Jetpack version installed?

I am new to using Jetson TX2,
After running the script from GitHub - jetsonhacks/jetsonUtilities: Get information about the NVIDIA Jetson OS environment. Lists L4T and JetPack versions, along with major libraries. I am getting below output.

NVIDIA Jetson TX2
L4T 28.2.1 [ JetPack 3.3 | 3.2.1 ]
Ubuntu 16.04.7 LTS
Kernel Version: 4.4.38-tegra
CUDA 9.0.252
CUDA Architecture: 6.2
OpenCV version: 4.1.1
OpenCV Cuda: YES
CUDNN: 7.1.5.14
TensorRT: 4.0.2.0
Vision Works: 1.6.0.500n
VPI: NOT_INSTALLED

Here it shows “JetPack 3.3 | 3.2.1” , so I am bit confused with the actual version available and why it shows two versions?

That’s the old version, you can use download SDK Manager, then follow these instructions to flash the new version. See JetPack SDK | NVIDIA Developer
