I don't think you've failed. Alcohol % rules aren't that tight - you get a 0.2% leeway anyway. FYI - Fruit Juice can contain around 0.7% alcohol per litre.
Also I think, but beers advertised as 0.0% - very likely have had alcohol removed from them chemically - which probably isn't that great. Something with a very low volume of alcohol content naturally occurring will be less so.
Sorry but they are tight and Brewdog are being investigated as their labelling is misleading
