Thread:Support/About MediaWiki:Antispoof-blacklisted/is

Hi, FuzzyBot added parameter 1 ($1) to the english original, but when $1 is added to the icelandic translation, the error message MediaWiki:Translate-checks-parameters-unknown is displayed. This error applies to MediaWiki:Antispoof-combining/is aswell. Is the parameter really supposed to be there or is this a bug?
