Sprite/Game Object labels in Animation panel are red?

After updating to 4.3 I opened the animation window, selected several sprites that I animated in the previous version. Noticed that some of sprites names/labels are red and the some of the sprite names/labels are the expected “white” font color. All of the sprites have their respective animation curves. The interesting thing is that when I run the game the sprites who now have red labels in the Animation panel no longer animate. While the the sprites whose labels are still normal in color animate according to their curves.

Anyone have any ideas on what the red labels signify? Is this something new in 4.3 and a way to show that the sprite is in some kind of “lock down”? Wondering how to get it unlocked.

If this existed in the previous versions I guess I was still to new at Unity to have it ever come up. Any thoughts or suggestions would be appreciated.

I’m having this same issue. What does the red signify? Did I screw up the sprites somehow?

Make sure your GameObject has a Sprite Renderer component so that Unity knows what Sorting Layer you want your animation drawn to.
