Yes you are confused because I am sharing you the CSS solution according to what is displaying on your site but it seems after using CSS code you are changing plugin settings which make the CSS solutions not to work.
To avoid this please tell me exactly what you are trying to achieve and configure the plugin settings accordingly then share me the plugin settings screen screenshot and don’t change anything in the plugin settings until i tell you.
For screenshots, you can simply provide a link to an image through Google Drive, Dropbox, screencast.com, https://imgur.com/ or other image service. ??
After this if there is any issue on your site then I can provide you CSS solution to resolve it.
Please note we have mentioned on the plugin page that “The styling of search form highly depends on how the theme styles search form” so it seems the zeeFlow theme you are using on your site doesn’t style it properly therefore we have to develop CSS code to style it.
