PBI Iphone app crashes when you try to create an alert on a card with a measure

Whenever I tap on the bell icon at the top to create an 'alerts' for a specific card on one of my dashboards the app immediately crashes. The specific card it does this on is displaying a measure, which is important because other cards that just use a field from the dataset seem to work just fine. Just so you know, the measure is using a calculate and sum function to display prior day sales. I'm using a iPhone 6s Plus on iOS 9.3.2 and the PBI app is up to date.
