Sprite Font 'Character width' property incorrect.
Set to 18 and it shows.
It also looks like your Character Set doesn't match your Sprite Font.
Your sprite font is 256 px wide, but only has 14 characters horizontally, which means that each character would need to be 18.28571428.... px wide.
You should ensure that - preferably - there should be 16 equally spaced characters horizontally, then the default width of 16 would be correct.
