Flex Repeater caching field values in perspective

The project includes a page where the user can start orders for different SKUs and a flex repeater is used to display the ingredients for the SKU. The user then enters lot numbers and temperature readings for each ingredient.

The issue is that when starting a new order the flex repeater is updated with new ingredients but the lot number text box and temperature numeric entry fields are not cleared. The flex repeater instances value is set to [] before being set to the new values so it should be cleared. I have confirmed that the new data has a blank lot number.

The only way to prevent this “caching” is to restart the view by navigating away from and back to the page. Is there a way to refresh the flex repeater that is more aggressive than just replacing the instances object.
