git commit shows a commit(a tex file) has 3054 lines added and 2996 lines removed, but use GUI tools showns only 60 lines added

Question

I'm using git under Windows, I use TortoiseGit or GetExtension as a GUI client.

I see a commit which changes a .tex, and from the GUI, I see 3054 lines added and 2996 lines removed.

But when I use the diff GUI tool, it only shows about 60 lines at the file.

So, is there any wrong with the commit?

I checked the EOL of this file, it's not changed.
