You need to check the order of things and whether you have more than one configuration file (ie, mysql.conf.d folder for example). We have had other reports were people believed that they had properly set MySQL settings but the variables were not reported by MySQL as they expected. Ultimately, it's a MySQL configuration issue.

Check all your mysql configuration files for a mistake as it's likely that one bad entry can stop the rest being parsed. Depending on your OS there is often more than just one configuration file. If in doubt, revert to default configuration and remove any customisations then start over.
