Schedule not showing in Firewall Schedules, are showing in Firewall Rules

[arriflex]

I suspect this is an upgrade issue although I'm not sure which upgrade may have caused it. At present my box is on 2.4.1-RELEASE. There are schedules which I created in a previous version of pfSense which are still showing in the Firewall/Rules/LAN grid as illustrated by the attached screenshot. However, there are no schedules listed in Firewall/Schedules and "none" is showing under Firewall/Rules/Edit Advanced/Schedule for either of the rules in the screenshot.

To be fair, it appears the Firewall is not respecting the old schedule rules and I could probably just create new ones to fix the basic problem but I don't like cruft;-)

Any suggestions where I should go to delete the old rules so that I can create new ones that work in the current release?

Edit the rule, make sure it has no schedule selected, then save. It should clear the old entry out of the rule.
