Configuration-specific mate values

When I was working on an assembly model in SW2011, I could assign multiple configuration-specific values to a distance or angle mate by highlighting the mate in the design tree, then double-clicking on the value in the graphics area. Since upgrading to SW2012, the values are no longer visible in the graphics area when the mate is highlighted in the design tree. What has changed? Why can't I see the mate value anymore? The mate features still show, but not the value.
