Export bug? Grid and axes are not shown in any format export
Using GeoGebra 6,
I have a problem while exporting a file as image (both in png and in svg format):
In the ggb I enabled the options "show grid" and "show axes" (I don'tknow if they are exactly so, I have Italian version, that's my translation) and while my work is opened in GeoGebra they are correctly shown. The problem arises while exporting: both in the png and in the svg file there aren't any axes nor grid.
I'm not able to save the ggb file (and so to attach it), here is the link https://ggbm.at/aYbWuhMV,
the png is attached.
