Reported repository size seems wrong

Hi, we have a repo, https://bitbucket.org/rbraswell/afolu_ccalc

And it now displays this message:
This repository's size is over 1 GB. Read more on how to reduce the size of your repository.

As well as reports the repo size to be 1.4GB. However, when I run this:

git count-objects -v -H I get
size-pack: 141.88 MiB

How can this be?
