Videos got lost

I'm currently working on a video series for YouTube, 12 videos total. I'm about 10 videos in now, with some videos being "goof off" videos that I toy around with presets, learning how to edit better, etc.

When I start up Premiere Pro, I see the past 10 videos I've worked on (8 legit, 2 goof off) but I don't see the first two that I worked on. 

I click on "Open Project" but it just pulls up my files and I haven't downloaded any of them yet. 

What happened to the first two videos?
