Jira Macro language problem

We updated our Confluence JIRA macro to 5.0.2 after our Confluence update to 5.2.3 (otherwise we had some errors).

Now we have the problem: When we use the Jira macro with a confluence profile language, that is not english, the macro delivers as result empty filters, but the preview still works.
The reason: It tries to use e.g. german column names, that Jira don't knows (see screenshots).
Result: Empty tables.
