Not sure about your individual situation. If you have three submissions available and only submit one on any particular day, that can knock you temporarily back to two. There is a recent dicussion about that here. imgflip.com/i/20y8vx Let me know if you want more info than that.
Try submitting two today, see if you are back to three tomorrow (or the next time you log in). If that doesn't work after a couple tries let me know if you like. I have have one or two more tips if you don't get back to three soon. Cheers!
