Add On Checkbox problem

Hi mate,

That element is because you used another plugin and it was not styled yet, so of course it is not the problem about the theme.
However, we will provide you a css file so that you can remove this without affecting into the other features

.ywapo_options_container .ywapo_input.ywapo_input_checkbox.ywapo_price_fixed{ display: none; }
Pls add this in Custom css in Customize

Hope that you can handle this issue yourself
Regards,
Yame
