lol, i think I see the problem now.
underneath your slider you've got "1.0E-5uF - 0.15uF", with the numbers in red & the units in black. And the text-entry boxes also have 'uF' in black.
But for me, on both Chrome & Safari (Mac), I don't have either of the 'uF' units in black!
hence my dummyspit.
(btw, it was just a normal Aussie dummyspit, nothing to be afraid of)
