You’re misreading the rule. Such titles are allowed.
If the title contains a gratuitous number or number + adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys." Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."
It's such a dumb rule to even have. If the article shows 10 Ways To Do X, then it is pretty accurate. How To Do X sounds like there is one way to do it, and it's being shown.
What happened to the don't editorialize rule, because that's exactly what's being done in the provided example. You're not just shortening an acceptable length title, but you've changed the meaning.
I see you've never submitted anything. I suggest you try a few times, deal with the automatic title mangling, and then come back and tell us how you feel about this rule ;)

Just the relevant bit:
translate "10 Ways To Do X" to "How To Do X"
