Git Request Pull: "Diff suppressed. Click to show." New lines are not new

Question

Everything!

After I clicked the files through git and want to make a pull request, it shows:

Diff suppressed. Click to show.like on screen

The problem is that the marked lines in the Pull request are new, but git shows that it seems to already exist (but it should be completely green). As you can see, the file is not too long, what's the problem?

And it looks like it only depends on the newly added files
