[Bug]: sieve rule getting added as external rule

[apollo79]

Description

A specific rule gets added / displayed as external rule (managed outside bulwark) AND as internal rule.

Steps to Reproduce

1. Got to Settings → Filters
2. Add a rule with content like this:
   • Match type: Any
   • Conditions: multiple conditions, I am using different "subject" "contains" and then "Report domain: mydomain.com" or "Report Domain: mydomain.com" or "Report Domain: {mydomain.com}" to filter for different dmarc reports
   • Actions: Mark as read and Move to folder
3. Save the rule and look at the filter / rule list

Expected Behavior

I expect to be added normally as an internal rule.

Actual Behavior

It gets added as internal rule but additionally gets displayed as external rule.
I also see it in stalwart, in the filters file doubled under the bulwark rules AND under the comment which indicates external rules, but removing it manually from the external rules doesn't make it work
