How to reproduce:

Create new 2D Core project
Add any 2D Sprite Sheet somewhere in the Project panel (e.g. Assets folder)
Select added Sprite Sheet and in Inspector select Sprite Mode : Multiple and click Apply button
Click Sprite Editor button > Slice > Slice > Apply
In Hierarchy create new object (2D Object > Sprites > Square)
Select created object and in top menu open Window > Animation > Animation
In Animation window click Create (and save animation)
Drag and Drop three sliced sprites into Animation window
Try moving added keys left or right
Check console for errors

Expected results: No error in console. It should be possible to move key frame left/right.
Actual results: Unable to move key frames in Animation window and multiple errors are thrown in the Console window if trying to do so.
