After changing some translations in translations.atlassion.com I downloaded the language pack for JIRA Service Desk and installed it into our instance but they show no effect.
I changed translations f.e. "My recent Requests" or "No Results found".
I checked the download pack and the translations exist.
The JIRA Service Desk Version is 2.1.
The possible versions for the lanuage pack wich I checked are 2.0md10 and 2.2.
