Bezier path moving during animation when it should not Stupid beginners question concerning animation.  I have four spheres which I would like to move along four bezier paths.  Three of them work correctly but in the case of the fourth the bezier curve ALSO moves: somehow the motion of that sphere in the Y axis has been replaced by the bezier curve moving in the Y axis instead.

I can't for the life of me determine what setting I've accidentally clicked on to make that happen.  Can anyone help me out?  This is in Blender 2.79b.

The Blender file can be downloaded from One Drive here:

It is "Suck Curve 2" carrying the animated sphere "Suck Sphere 2" which is the problem.
There are several ways to do it:


F3 and type Remove Animation.
You can delete the animation in the Outliner: Select the object, unfold its tree, right click on Animation and choose Clear Animation Data.
Open the Dopesheet, switch it to Action Editor mode, you have a dropdown menu with all your animations, close the selected animation with X.


As your curve was the only user of this animation, it won't be reloaded when you'll reopen the file. If you don't want to loose it, in the Dopesheet / Action Editor mode, on the right of the action name (it has now a 0 which means no user), press on the shield icon.
