Well, please note that in the left border where the tracknumbers are all 'eyes' are crossed off apart from the eye in track 1. Even the subtitle eye has a bar or back-slash, which means that (all) these track are not shown and not produced.
Right click with the mouse on all the tracks you want to be visible and I recon that the subtitle and the stuff in other tracks will become visible.
what (also) strikes me is that you have a lot of gaps between the clips in track 1. If there are no visible clips in the tracks below these gaps, you will see black screens on these places in your production.
The tracks below do not show on the picture, it may be that you have something to show there:
let us know whether un-slashing the eyes has solved your problem....
