I have ctags installed on my machine through Homebrew, but I haven't generated any tags files. However, when running the command :h word I get the following two errors:

E432: Tags file not sorted: /usr/local/share/vim/vim81/doc/tags E426: tag not found: b:match_word@en

I'm not sure how to go about fixing this. Is there a default tags file included with Vim for the help system? I have the youcompleteme plugin installed, would that mess with tag functionality?
