iOS 9.3.2 - Siri Suggestions Shows Wrong Contacts
Finally figured it out!!! That person a long time ago had invited me to a Facebook event that last many many days in a row. I never declined or ignored the event and I also had my iOS calendar set to show Facebook events. I declined and ignored the event in Facebook, he still appeared, but I didn't wait long (maybe that takes a while to refresh). I was impatient so I just turned off showing my Facebook events in the calendar app all together. He finally disappeared.
