Hi!
Thank you for all the details.
When a block is displayed multiple times, it is usually related to a 3rd party script, but I am not sure in this case though.
I assume you want a two-block layout, where the settings block is on the left side, and the search bar on the right side, something like this: https://i.imgur.com/uxbv3mO.png
To achieve that, simply use this shortcode alone, nothing else at all:
[code][wd_asp elements='settings,search' ratio='50%,50%' id=1][/code]
(just change the id parameter, for the search ID you have)
This should do the trick, your settings seem to be all right to me. You can construct these types of shortcodes with the Shortcode Generator feature. Let me know how this works out!
