PopBox appears behind column and text

Hi, after creating a One-click button popbox, the box shows up behind the column and text when clicking.

I have tried changing the z-index to 9, re-doing the page, but nothing works.

I don’t how to attach a screenshot, but the description is exactly ‘the box appearing behind the column and text’.

Thanks very much for your help, this is quite urgent as clients are using it. I appreciate your time.
