When Right clicking and selecting add key frame to an animation on the curve editor in UMG there appears to be multiple keys being added to the timeline.

Steps to Reproduce
  1. Open editor
  2. Create a new Widget Blueprint
    Right click content browser > User interface > Widget Blueprint
  3. Open the new widget blueprint
  4. Add a button to the designer graph
  5. Add a new animation
  6. Select your new button and a keyframe for the X position of the button (attached image for reference)
  7. Move the scrubber bar to 3 seconds
  8. Change the X position of the button and add another key frame (the button should now go left and right when scrubbing the timeline)
  9. Open the curve Editor
  10. Move the scrubber bar to about 1.5 second and right click > add key frame
  11. Notice the timeline freaks out and that multiple keys are added (image attached for reference)
