How to reproduce the issue

I think this might be something wrong with my config instead since no one else has this issue.

This is my complete config file. Copy pasted from the readme. Not exactly sure what's the issue but the folds are not being highlighted and there seem to be numbers at foldcolumn?

I'm using catppuccin theme with transparent background. Tried turning that off but it still didn't appear.

vim.o.fillchars = [[eob: ,fold: ,foldopen:,foldsep: ,foldclose:]]
vim.o.foldcolumn = '1'
vim.o.foldlevel = 99 -- Using ufo provider need a large value, feel free to decrease the value
vim.o.foldlevelstart = 99
vim.o.foldenable = true

vim.keymap.set('n', 'zR', require('ufo').openAllFolds)
vim.keymap.set('n', 'zM', require('ufo').closeAllFolds)

local handler = function(virtText, lnum, endLnum, width, truncate)
  local newVirtText = {}
  local suffix = ('  %d '):format(endLnum - lnum)
  local sufWidth = vim.fn.strdisplaywidth(suffix)
  local targetWidth = width - sufWidth
  local curWidth = 0
  for _, chunk in ipairs(virtText) do
    local chunkText = chunk[1]
    local chunkWidth = vim.fn.strdisplaywidth(chunkText)
    if targetWidth > curWidth + chunkWidth then
      table.insert(newVirtText, chunk)
    else
      chunkText = truncate(chunkText, targetWidth - curWidth)
      local hlGroup = chunk[2]
      table.insert(newVirtText, { chunkText, hlGroup })
      chunkWidth = vim.fn.strdisplaywidth(chunkText)
      -- str width returned from truncate() may less than 2nd argument, need padding
      if curWidth + chunkWidth < targetWidth then
        suffix = suffix .. (' '):rep(targetWidth - curWidth - chunkWidth)
      end
      break
    end
    curWidth = curWidth + chunkWidth
  end
  table.insert(newVirtText, { suffix, 'MoreMsg' })
  return newVirtText
end

-- global handler
-- `handler` is the 2nd parameter of `setFoldVirtTextHandler`,
-- check out `./lua/ufo.lua` and search `setFoldVirtTextHandler` for detail.
require('ufo').setup({
  fold_virt_text_handler = handler
})
