Upgraded to Mojave 10.14.1 — where has all my storage gone?!

[Craigus_uk]

Hey.

I've just upgraded to the latest Mojave 10.14.1 release and was a bit surprised to find that my SSD is only showing that it is 250.69GB (strange number) in size as apposed to the 512GB it actually is, and was, before i updated to macOS 10.14.1.

My system specs:
15inch, 2017
2.8GHz i7
16GB Ram
512GB SSD

I've restarted, run first aid through disk utility and aren't really techy enough to know what I can / should do to fix the problem. Any ideas are much appreciated.

Thanks!
