High Sierra 10.13.6 update, ram and storage bug

Hi,

I have a MacBook Pro 13" 2017 (2 thunderbolt C ports), 16GB Ram and 512GB storage.

Since updating to 10.13.6 my ram has been showing up as 8GB and storage as 250GB.

However, when I click into system report and move to the memory tab, I can see that both memory slots are in use with each holding 8GB ram = 16GB ram total.

Can anyone tell me why the MacBook is not recognizing the actual ram/storage in the About this mac section?
