Odd phantom level appears when I plot two levels

[LukasWallrich]

When plotting just two levels, a third unnamed phantom level appears - when I add a 0, there are no longer any phantom boxes, but the level still pollutes the axis. No idea what is going on ... would be great if this could be fixed if/when this package's development is revived ...

parts <- c(80, 30)
waffle::waffle(parts, rows=8)

parts <- c(80, 30, 0)
waffle::waffle(parts, rows=8)
