I submitted stuff to both of your streams but don't see them yet when I sort by latest. I think your settings are configured that you need to approve some or all submissions to your streams.
There should be a new button called "Approval Queue" in here
imgflip.com/my-streams Click that button, if you see your streams in the dropdown list, click one of them. Depending on your stream settings, you might see a new card with stuff to approve what users are submitting to your streams. Green check to approve submissions to your stream, red x to keep it from showing on your stream.
