Negative numbers in option menu

[Kaveh Bazargan]

I have an option menu button containing a series of numbers for the option,
including negative numbers. These numbers show fine when I inspect the
"text" of the button, I see these including the negative numbers. But when
I use the button, all the negative numbers come out as blank spaces. Can I
use negative numbers in option menus?
