I noticed in Excel 2016 Estonian (ET-EE) a duplicate translation for a special item specifier for structurated references in tables. The screenshot below visualizes the problem.
In Estonian, #All and #Data have both been translated to #Kõik. This should not be the case, as then e.g. a formula would be ambigeous. Maybe, the error is also present in previous versions of Excel. However, I did not check that.
