Cannot see an element in my movie

1

I am a little puzzled as to why part of my movie is not showing up.

Everything works fine but there should be a line motion from the gun to the backpack. I see it on the stage when I manually drag the time line but on line and even when I publish off line I do not see it.

Any help will be appreciated.
