My first guess would be, it's A-12 category that you need to file an application on. There is another category, I think it's C-19 or something which is for the first time TPS filing and requires both I821 and I765 application. But once you get a TPS approved you file I765 with A-12 category stated on your application.
Coz in my facially expired EAD it says A-12 Category and my application to replace EAD was approved a month ago where I used the same A-12 Category. Please check your application if you have the PDF and confirm that you have the right category filled out.
