Screenshots that don't include the modified properties of the layer you are having problems with do not provide enough information to point you to a solution. Try selecting the layer, press the U key twice to reveal all modified properties and then print screen and paste to the forum or Shift + Ctrl/Cmnd + 3 on a Mac and drag the full screenshot to the reply field. Then give is a complete description of the workflow and what's happening in the timeline.
There are a dozen things that could be causing this problem.
Well, at least they're screen shots. But we need to see the keyframes, not an empty graph editor.
Ok, now try this. Start by soloing the "Glass to Shatter" layer. Do you see anything? What is on that layer? Is there a hole it it? I can see that it's a comp but if you have something like a picture of a glass in the comp then it should have a transparent background so that all of the layer shatters. If you want a hole in a white solid then it makes no sense to have a white background.
Next start resetting some of the values. Start with Texture Opacity. when the lines go away you've probably found your problem. Personally I think you just have not set up the composition properly.
We still don't know what you are trying to accomplish. Also, it doesn't make any sense to keyframe the repetitions because once the shatter starts the number of pieces stays the same.
Okay, I played around with the Texture Opacity like you suggested, and I got the effect I wanted.
Basically like I said before, I wanted the logo, which is on a white background, to shatter and fall apart without the hole in the back.
Thank you once again.
