Problem with Onetone Metabox Options

Hello,

I will present my problem and I apologize if my English is not very good.

Onetone Metabox Option does not display the right values for Padding Top et Padding Bottom. In fact it seems that Padding Bottom always display the same value as Padding Top.

Let me explain:
If I put to 150px for Padding Top & 50px for Padding Bottom, after saving, Padding Bottom display 150px. However, the real padding bottom in my CSS is 50px (that is good !).

whatever the value i put in Padding Top, after saving, Padding Bottom display the same.

Do you know how I could fix this ?

it’s very annoying to not know what value was entered in the page’s interface.

Thank you.
