Popbox doesn’t load

Hi.

I have this plugin working with tabs PRO (Tabs Pro wpshopmart). In each tab I have a button that open a form. The strange thing is that only one button works…
I’ve checked the ID and looks ok…

<div class=”agenda”> <span class=”elementor-button-text agenda”>PLANEIE A SUA VIAGEM</span></div>

Can you help? Thanks
