In Czech Republic comma is used for decimal points. But in the Juice amount it seems more like a bug. But I don´t know how Unity engine uses locale features or thing like that. But as it uses C#, I think that this programming language might use the locale of the computer for setting things like time, etc. But there it´s weird and it more looks like some bug, as it uses comma instead of space between numbers (is that intended with point instead?) and then point instead of a comma for decimal part of number.
