My github repo is not showing the language I have used

[CalmJiad]

Hi everyone,

I have an awkward problem that I can't seem to resolve. The languages used in my repository are not being displayed correctly. I attempted to modify the .gitattributes file, as suggested on Stack Overflow, but it didn't seem to have any effect. Can anyone help me figure this issue out? Thank you in advance!

And by the way, this is a public repo that I am having the problem with, you may have a look at it:
