Unable to change plugin language

Hi!

I am not able to change the plugin language for some reason.

I downloaded one of the .mo files (es_ES) and copied it into /languages/edd/ but this doesn’t seem to be working.

I have my site language already set to Spanish, not too sure what else I can try?

Thanks for your help
