Help me minimize the font size for "continue" & "Restart" buttons in the page that appears when user resumes!!!

Hi.... there is a situation and I'm mandated to added the word 'Module' to the 'Continue' and 'Restart' Buttons on the resume page. I Figured out that if can be changed using text label. But, I guess it exceeds the button text limit and goes out of bounds(Please check screenschot attached). I've no clue how to reduce the font size. Reducing 'Player font size' does not change it. Help much appreciated :)

Thanks!
