iOS: Sometimes broken intelligence classifiers are created

[Limero]

Sometimes when I create intelligence classifiers in the iOS app, they don't behave as expected, even afterwards on the desktop website.

I recently created a negative filter for Hacker News to hide posts with "is hiring" on iOS and now it always treats it as positive, even though the API response and settings shows it as negative.

Response from /reader/feed/6327282

{
	"titles": {
		"Ask HN:": -1,
		"hiring": -1,
		"Ruby": -1,
		"AI model": -1,
		"New Glenn": -1,
		"Is Hiring": -1
	}
}

I've tried flipping the identifiers back and forth between negative/positive and removing the site completely, but I can't get rid of this.
