From the screenshot it seems like a cache related issue only, although I cannot tell exactly. I don’t think it is related to the search configuration. I see you have all the stylesheets and script files cached. After making changes in the production, make sure to clear that cache as well. That could explain the problem.
Perhaps you can enable this option if you want to: https://i.imgur.com/4ii85Gi.png
That will load the search styles asynchronously, bypassing the original cache.
