TTF Font Size Issue (Bug?)

So, I added my TTF font, and there's no way to lower the font size.  Under the "Size" peramiter there's a weird box thing with 4 columns.  When I click on one of the numbers, it just increases.  How do I decrease the size?

left click = increase

Im not sure why the size selection has this weird input. Would love to see a normal input box or at least some kind of "spinner" there.

Me too. I don't like that thing and it drives me crazy...
But I think that is for decimal point numbers only

Ah, got it.  Thanks!
