Bundled plugins' cheatsheets aren't loading

[Widowan]

For example, I have vim-sandwich installed, however it's cheatsheet (which is apparently bundled) doesn't load.
After investigation, I found out that plugin_include table in init.lua forms weirdly, with trailing slashes.
Here's what print(vim.inspect(plugin_include)) says:

Output

{
enabled = { "nvim", "nvim", "site", "packer.nvim", "site", "site", "runtime", "matchit", "nvim", "vimfiles", "cheatsheet.nvim/", "completion-nvim/", "completion-tabnine/", "kommentary/", "
nvim-autopairs/", "nvim-lspconfig/", "nvim-treesitter/", "nvim-ts-context-commentstring/", "nvim-ts-rainbow/", "onedark.nvim/", "packer.nvim/", "plenary.nvim/", "popup.nvim/", "suda.vim/", "
telescope.nvim/", "todo-comments.nvim/", "vim-easy-align/", "vim-sandwich/", "vim-smoothie/", "vim-xkbswitch/", "which-key.nvim/", "after", "after", "after", "after", "after", "after/", "aft
er/" }
}

It may or may not be related, perhaps I'm missing something obvious...
