Rails eager loading with WHERE clause results in two SQL queries

I'm trying to eager load a Course model with some associated models, Community and Package. The relationships between them are as follows:

class Community < ApplicationRecord
  ...
  has_many :courses, dependent: :destroy
end

class Course < ApplicationRecord
  ...
  belongs_to :community, optional: true

  has_many :package_course_relationships, dependent: :destroy
  has_many :packages, through: :package_course_relationships
  has_many :available_packages, -> { available }, through: :package_course_relationships, source: :package
end

class Package < ApplicationRecord
  ...
  has_many :package_course_relationships, dependent: :destroy
  has_many :courses, through: :package_course_relationships

  scope :available, -> { where(archived: false) }
end

class PackageCourseRelationship < ApplicationRecord
  belongs_to :package
  belongs_to :course
end

The problem I am facing is that when calling

Course.includes(:community, :available_packages)
      .where(communities: { is_active: true }, archived: false, is_draft: false, is_completed: false, is_default_template: false, visibility: %i[unlisted public])
      .find(3)

two sql queries are made:

SELECT DISTINCT "courses"."id" FROM "courses" 
LEFT OUTER JOIN "communities" ON "communities"."id" = "courses"."community_id" 
LEFT OUTER JOIN "package_course_relationships" ON "package_course_relationships"."course_id" = "courses"."id" 
LEFT OUTER JOIN "packages" ON "packages"."id" = "package_course_relationships"."package_id" AND "packages"."archived" = $1

I am not very experienced with Rails and I think I might have written the ActiveRecord call wrong, but I can't guess why this is resulting in two similar SQL queries.

I don't really know what to try, but I am expecting only one query to be made. It is confusing to me why the first query that only selects the id of the course is made.
