"disable or limit SHA-1 certificates" is about certs, not ciphers.
Because CERTS is 1st in the title I moved it to the 1st item there because it's arguably also the most important of the lot (and renumbered the rest)
We can also drop HSTS from the subgroup title because there's nothing HSTS left atm.
