Summary
It seems that the Transform node does not properly adjust when moving keyframes set for Rotation and Scale.

1. Create a sequence and add a video clip to the video1
2. Create the following nodes attached in this sequence:

Text-->Stroke-->Blur-->Transform-->Math--
___Merge
/
Media file-->Blue-->Transform-->/

3. Three seconds into the video first set keyframes as set as follow:

Rotation: 0
Scale: 100%

4. One second later set another keyframe as follow:

Rotation: 10
Scale: 125%

5. One second later set another keyframe as follow:

Rotation: -10
Scale: 75%

6. One second later set another keyframe as follow:

Rotation: 0
Scale: 100%

7. This above works fine so far, but then attempt to move set of keyframes created in step Olive has no sound support #4 thru 6 by selecting them and moving them to the right

8. Play the video and the animation of the transform no longer works as expected.

Additional Information / Output
The playback when moving the keyframes are not working as expected. Please see attached video
