Allot of settings reverted after updating asus GT-AC5300

[Enzorogggg]

I have recently gotten 2 firmware version updates and im currently at 3.0.0.4.384_82037

I noticed that most of my settings seems reverted to default almost like a factory reset.

port forwarding ports is now reverted to no ports open

aiprotect detection is now 0 detectins.

There were some other stuff too which i cant remember right now but its similar behavior.

Is this behavior normal after software update or should i be woried?.
