I couldn't reproduce the issue on the CE image.

Here is what I found irregular:
1)If I first create a separator (on an empty list) then create a rule, the separator gets deleted.
2)Deleting any rule will delete the separator.

I was able to reproduce this, and it looks to affect both firewall_nat.php and firewall_rules.php.

Neither adding or removing separators will work when no rules exist.

At least part of the issue seems to be here:
https://github.com/pfsense/pfsense/blob/532be9051b3e633507ec864394b825a7a69a4bec/src/usr/local/www/firewall_rules.php#L218

The code to update the separators only exists within the code that checks if rules exist. Hence, if no rules exist, separator additions are not updated.

PR has been merged. Thanks!
