Some TeX snippets don't expand according to config

[angelus2014]

I just started (so please excuse if this is a stupid question) using vim-snippets (Neovim 0.7.0) with ultisnips, but I've noticed that with LaTeX (tex.snippets), there are several that expand differently.
For example 'bf' expands to '\bf{}' even though in the config it states:

snippet bf "Bold" wi
  1 \bf{${1:${VISUAL}}}$0
  2 endsnippet

Also, shouldn't 'bf' be 'textbf' as with 'bf' the rest of the text will be bold, not just the text inside the brackets...... When using just bf, it should be {\bf text-one-wants-in-bold}.

For what is worth, I agree: the \bf syntax is awkward and it is not correct, a workaround might be to switch \bf and the opening brace as follows: {\bf ${1:${VISUAL}}}. All in all, personally, I do prefer \textbf{}. In fact, a quick search through the history shows that it used to be implemented version until a couple of months ago, commit ddcda4f; notice that since then, more recent commits reverted some changes applied by the former. Actually, the original snippets are still presents in snippets/tex.snippets, however they are overridden by those in UltiSnips (if you are using UltiSnips, I guess).

Notice also that similar problems hold for snippets it, rm, un

if you not set like this

vim.g.UltiSnipsSnippetDirectories = {
  vim.fn.stdpath("data") .. "/site/pack/packer/opt/vim-snippets/UltiSnips/"
}

in default, this ultisnip plugin load this snippets/ directory, not the Ultisnips/ directory, this will not be overwritten by Ultisnips/ directory @angelus2014
