Password Manager Wrongly Identifying Twitter Breach

I just wanted to report to the team that Twitter is being wrongly identified in the UI as being breached. I double checked this to make sure using...

https://haveibeenpwned.com/api/v2/breaches?domain=twitter.com

As you can see, no response.

Any idea why the Password Manager UI would mark my twitter password as breached? Password is not a problem as also checked.
