different ospf timer values

Hello,

I have configured my Fortigates on OSPF protocol with hello timer = 1, dead timer = 4 by using GUI.
To be sure, I checked them by CLI. Everything goes fine.

But when i run "get router info ospf interface" command, it showed hello timer = 10, dead timer = 40.
I didn't know where they come from and why they are changed.

My FortiOS is 6.4.1

Thank you.

Looks fine, though I would only set them like this in lab testing. 
This is on 6.4.3
