How to remove this class on load: ywapo_conditional_hidden

We have two radio buttons with first already checked, and additional checkboxes that appear depending on which radio button is checked.
The problem is that when page loads with first radio button already checked, additional options doesn’t show automatically (they are being hidden using “.ywapo_conditional_hidden” class). This behaviour is strange, because Option Requirements are being met on page load already.

1st radio button’s options appear Only when I select second radio button and then again the first one.

I tried to remove “.ywapo_conditional_hidden” class onLoad, but it doesn’t work, since “.ywapo_conditional_hidden” class is being added onLoad by the plugin.

Is there a solution for this?
