Github Pull请求显示更改的文件多于命令行?

我正在尝试向 develop 分支 venmo 存储库 CC-132-Not-enough-balance-decline-notification 我的分支存储库位于 kupeek 远程的GitHub上的pr表示30个文件已更改:

但是,如果我只是做一个 git diff 在本地,我只看到16个文件发生了更改:

LM-SFP-21018636:venmo-android kupeek$ git branch
* CC-132-Not-enough-balance-decline-notification
  CC-132-refactor
  CC-132-use-generic-notification
  CC-563-remove-shift-card-id
  develop
LM-SFP-21018636:venmo-android kupeek$ git diff upstream/develop..HEAD --name-only | wc -l
      16

在我做了一个 git fetch upstream develop -也就是说,我非常肯定我正在将其与该分支的最新版本进行比较。

怎么会有差异呢?我做的是合并一个实验分支, CC-132-refactor 同时重新平衡 upstream/develop .
