Lineup Optimizer Not Reaching Every Player

I have over 400 active players in my personally created projections. The sheet that I have to download and reupload only has 224 players. Because the ID's are required, I'm missing 200 projections. Can I create custom ID's?

For players not visible on our site, you won't be able to add projections. We only include players from the DFS site players feed. Every player with a salary on a DFS site for the week should be in Colossus. Are you seeing players on Draftkings.com and Fanduel.com that aren't in Colossus?
