Cannot import package: Typography with id: "Default" already exists

So before export, changing Typography name used by the Custom container from 'Deafult' to let say 'DeafultExp' resolved this issue.

Hm, so there must be as many different Typography names as number imported Custom containers ?

Gfx understands that the 'DefaultExp' and 'Default' are the same Fonts and asigns them the same Id:

static const touchgfx::FontId DEFAULT = 0; // verdana_20_4bpp

static const touchgfx::FontId DEFAULTEXP = 0; // verdana_20_4bpp

struct Typography
{
 static const touchgfx::FontId DEFAULT = 0;
 static const touchgfx::FontId LARGE = 1;
 static const touchgfx::FontId SMALL = 2;
 static const touchgfx::FontId DEFAULT1 = 3;
 static const touchgfx::FontId DEFAULTEXP = 4;
};

struct TypographyFontIndex
{
 static const touchgfx::FontId DEFAULT = 0; // verdana_20_4bpp
 static const touchgfx::FontId LARGE = 1; // verdana_40_4bpp
 static const touchgfx::FontId SMALL = 2; // verdana_10_4bpp
 static const touchgfx::FontId DEFAULT1 = 0; // verdana_20_4bpp
 static const touchgfx::FontId DEFAULTEXP = 0; // verdana_20_4bpp
 static const uint16_t NUMBER_OF_FONTS = 3;
};
