STEPS TO REPRODUCE
1.  Create an Image Sequence.
2. Add Image Sequence to Video Track using a Frame Duration of 00:00:00:03
3. Change the Clip speed to 200%

OBSERVED RESULT
The clip is sped up, but the Video in the Project Monitor is only about 60% of the original clip as shown in the Clip Monitor.
In attached screen shot, you can see the playback position at the end of the Project Monitor and the playback position of the Clip Monitor for the same frame.

EXPECTED RESULT
The whole clip should be used and sped up by 200%
