This is a reoccurring problem that happens when you try to link a comp through premiere using cinema DNG files. Once it opens in AE you only see one frame. Adobe has stated it's a known problem but still haven't fixed it. Most will just replace the single image with a new sequence but the problem is you have to reset the in and out points manually. However, if you right click the dng file in the project window and go to Replace Footage>File and find the new sequence it will replace it in the comp with the correct points and will translate to premiere live. Just thought I'd share this tip as I didn't see any other post about it.
Thanks for posting in Adobe forums. This issue is fixed in the latest update of AfterEffects in April 2017(14.2), Please update to latest version.
If you are facing the issue even after the update to 14.2 version, please let us know.
