Why Bitbucket cloud is showing a different size than my local repo?

[-----]

Hello, in Bitbucket shows a size of 1.7 GB  but my repo locally less when I run "git count-objects -v". Am I missing something here? Is Bitbucket Cloud counting something else? I haven't change anything locally and did a git pull.
