In your original post, you mention:
The theme is a heavily modified: https://themes.gohugo.io/meghna-hugo/
We have no idea how you modified this theme. We cannot possibly guess what these modifications are. Maybe you added CSS display: none. Maybe you got some JS magic. Based on the limited information you provide, it seems the HTML code for that div does get generated, so I can only guess that it’s probably a CSS/JS/whatever going on.
We are not asking for your site code just for funsies. If you had taken the time to read the Requesting Help guidelines you would have seen this section:
Let us see your code
Include a link to the source code repository of your project, because we really need the context of seeing your templates and partials to be able to help you. It is trivial to do a quick
git cloneon your repo, then runhugo serverin your project, to help you out. On the other hand, recreating your code from screenshots, or sort of guessing at it, is not.If you can’t share your repository for whatever reason, consider creating a dummy repo that you can share, which reproduces the problem you’re experiencing.
If you are unable to understand this, we are unable to help you.
Good luck with whatever issues you are having. You are welcome to ask your question again once you have read, understood, and complied with the Requesting Help guidelines.
