Service Desk SLA images missing on Boards

A Kanban Board containing a Card with "Time to Resolution" field doesn't display the Service Desk SLA images on the board as it used to.

Environment:
JIRA 7.0
Agile 6.7.11

Steps to reproduce:

1. Create a Service Desk Project
2. Create a Kanban Board of that same project
3. add a Card with "Time to Resolution" field from the "Card Layout" Board configuration
   Result: Board shows only a number with the field data
   Expected: SLA image and color is displayed along with the data as it does on Service Desk or in a JIRA Issue Search.
