Strange update numbers

Hello! I’m installing some World Updates however it says it’s installed 55.72GB of 15.70GB.

How does this make sense? it’s normally how many GB you’ve downloaded / how many GB in total.

Hi there, Are you on XBox, PC, MS Store or Steam?

sorry, this is Steam

You have selected 7 packages for installation, which is why the download size is 55GB.

the first number is supposed to be current download and the second number is supposed to be total download
