RDLC Textbox Line Spacing

I am making an RDLC report and I have placed a textbox and typed in my text (17 lines). I am wondering if there is a way to change the line spacing between my lines in my textbox?

I tried setting the Text Box Properties, Font, Line Spacing to custom 1.5pt but it doesn't change anything. Anyone know what I am doing wrong?

Thanks,
Stacy
