nividia-settings output different from nvidia-smi output

Hi,

I install the Nvidia driver 390.116 on Ubuntu 18.04 for my GeForce GTX 1080 graphic card.
I also install the CUDA 9.0 Toolkit.

When I type nvidia-smi in the terminal, I obtain this:

When I type nvidia-settings --version, I obtain this:
nvidia-settings: version 418.43
The NVIDIA X Server Settings tool.
This program is used to configure the NVIDIA Linux graphics driver.
For more detail, please see the nvidia-settings(1) man page.

Should it be the same version (i.e. 390.116) ?
From https://www.nvidia.com/download/driverResults.aspx/142958/en-us it seems that this settings support GeForce 1080 GTX.

Thanks
