Part of a clip offline, no gray bars.

I'm trying to reexport an old project but a few clips from my timeline appear as if part of them is offline. However, they don't show any gray bars. If I double-click on the clip and watch it on the viewfinder I can see it in its entirety.

I deleted all the previews, unlinked the media and linked it again. I replaced the media with the same file that was originally saved in a different folder. I tried selecting the clip from the viewfinder and dropping it back in. I even tried copying the files and pasting them to a new sequence because I realized that if I moved the clip to a different part of the sequence I can see the whole clip.

I don't know what else to do or what the problem actually is.

Does anyone out there know?
