Just wondering...why does the stadium info on SB athletics website say that the "seating capacity" is 12,300?

It says that "expanded in the summer of 2017 to its current capacity of 12,300".

Wasn't the seating capacity 8,200 before and now with additional 2,000 total would be 10,200? Does the seating capacity of 12,300 include standing attendance?
