Did you make any last minute changes with your application? Go over the conditions for eligibility under your program (FSW, CEC, etc) and make sure they are met with all the details you've provided.. I don't remember if it was exactly like this but I ran into a similar hurdle when applying. In my case, it was a last minute change of primary NOC code and the job that gave me the 1 year continuous employment (FSW requirement) was not matching with the primary NOC code, so I was losing eligibility under FSW and noticed similar issues..
Either that or maybe it's just a technical issue. If you're sure all your details are correct, send them a webform mentioning the problem:
