Accordion not expanding

Hi. I am building a new site and testing your plugin but am having a problem with some shortcodes not working – I have tried a couple of accordian style shortcodes and neither expands the text when clicked if the code is in a widget within a Page Builder row – but the code works fine when added to a ‘normal’ post or page.

There are a few variations on this page in the ‘Programme’ sections:

I have used the Visual Editor widget and tried pasting the code in a simple text widget as well, but in neither case does it function. I’ve tried deactiviating other widgets and plugins and that did not appear to affect the issue.

Any ideas would be appreciated.

Thanks.
