frames missing, but have their annotations

[Peng Zheng]

When I ran my code, I found that in movie tt6513406, I have the annotations of shots after shot_2071:

But actually, the frames of shots provided are < shot_2071:

I downloaded the keyframes.zip twice, there should not be problems with the completeness of my file.

Since the frames are annotated, I guess those frames should have been selected as keyframes but went missing accidentally?...
