Hi there, NY!  I'm not sure why your slide was initially 1000 seconds-  did you have any media files that lasted that long?  The timeline will default to the longest lasting item/file.  For a quick way to shorten the timeline back to 100 seconds, you can click the end of the timeline and start dragging, and then press your left arrow key at the same time.  It will zip the timeline back to the end of the longest content item.  Here's a video that explains further!
