Timer Digit Font Size Not Changing

No matter what I change the value to on the “Timer Digit” size, the timer is small.
This is weird however, as when I first installed the plugin, the timer was “reasonably sized” whereas now, it’s just tiny and a waste of time.

Have copied, created new, made various modifications to the settings, but can’t seem to make it work…
