Hummingbird Minification not seeing changed files

I have an issue where hummingbird says “PENDING” next to a css file. It didn’t like the @import declaration so I removed it and then reuploaded the file and reran minification. Minification just not recognizing it has been changed.

I have all caching turned off including browser caching from within hummingbird. I’ve verified a the offending issue within the css file that said “PENDING” had been removed by visiting it in a browser. I disabled minification and had it rerun the test. I’ve even renamed the file, then ran minification and renamed it back, then reran minification to no avail. It STILL says “PENDING” how can I stop that?
