See for instance the URL, which is one provided to translators, not provided by the extension itself (there's no taction parameter). It doesn't depend on skin and it's a bit confusing because you see a proofreading task in the translate tab/view (with neither of "Show all messages" and "Show untranslated messages" radio buttons selected).
Thanks for the report. This has been fixed in TUX.
