Minification files are gone


I have a problem, i try to find information about this but cant find it.

Hummingbird ---> Minification, when i go into that page and check which file is in the footer, header and original, there is only one file.

I cant get the other files back (there use to be many files), i re-check files and so on and nothing works, still just one file. I try the filter also, nothing happend, just the one file there.

The file who is visible is this: accelerate-pro/style.css

I dont know where they are and what happend! I can see that i have same problem on several sites, maybe all.

The file there is are the one who is "original"

Thank you in advanced!

Kind regards,
