Disabling RAM Disk doesn't remove schedule from /etc/crontab if schedules aren't disabled

After enabling the RAM disk I also scheduled the two periodic backups for DHCP and RRD to run.
This created entries in /cf/config/config.xml and crontab as expected.
When I disabled the RAM disk feature I forgot to disable the schedules first. As a result the two cronjobs still are listed in /etc/crontab.
