Duplicate prefixes

[qbnil]

Is there any way i can only leave one prefix sign all the time. Right now there are cases when these are getting multiplied for some reason like here

And the main thing, the signs are not getting highlighted. It'd be cool if i either get everything highlighted or only leave one sign icon..

I don't use virtual text so I'm not sure how to do it. I do know you can configure virtual text using vim.diagnostic.config(). And here are the properties virtual_text supports opts.VirtualText.

So, call vim.diagnostic.config and setup the virtual_text property.

vim.diagnostic.config({
  virtual_text = {
     ---
     -- here you configure whatever options you have available.
     ---
  }
})
