Timeline help

Hi, I’ve got what seems to be a really strange bug. I have a scene with a few different objects in it, all with keyframe animations. One of the objects though seems to have it’s keyframes permanently displayed in the timeline even when it’s deselected? When I select another object, that objects keyframes are then shown as well as the original, then deselecting everything again still leaves the problem objects keyframes visible.

The scene didn’t start this way so it’s something I’ve accidentally done or turned on along the way?!?

Any help would be great as it’s driving me mad!

Thanks.

J.
