Dropdown Menus Displayed Twice During Pilot but Not in Preview

Hello,

I’ve incorporated several dropdown questions in my Pavlovia Surveys, which display correctly in the preview mode. However, when I pilot the survey, each of these questions presents two dropdown choice bars instead of one.

Notably, the first dropdown bar lacks the “None” option,

which is present in the second bar.

This issue does not affect dropdown-type questions within a multi-select matrix.

I have tried different layout settings and choices settings (ex., don’t use the “Allow None Option”). And I happened to find some demos offered in another post on a different subject, where I found also duplicate dropdown menus. 'Other' option not appearing when survey is running (works in preview) - #6 by wakecarter

Could anyone offer insights or solutions to this problem? Thank you for your assistance.

Best regards,

Shiyu
