Sublime Text 3 comment symbol//After the text still has color (originally should be gray) why?

Today I do not know where the tune has become this.
Is there a way? I've been looking for a long time.

In the lower right corner, you can choose the right language.

Your comments in this language seem to be # rather than//

Should be related to the theme you use, there are different languages to identify the comments show different colors
If you try another language, the comment will not be grayed out, and if it does, this topic does not adjust the comment color of PHP.

In different languages, the editor differs from annotation symbol parsing.

That's the first floor.

Is it because the parsing mode of the selected text, such as Java, is // commented and some configuration files are #
