I've never seen the waiver wire glitch like that in my 13 years on the site. You can always send a ticket into customer support, and see if they can help. However, in most cases where I've heard people talking about glitches, it usually turns out to be user error. Make sure you've read all the FAQ on how the waiver wire works.
Pro tip: The waiver wire is almost always a bad idea, since it costs you a 10% penalty in salary each time you use it. Until you've learned what those fringe cases are, stick with the team you drafted and give your guys the chance to live up to their potential instead of losing salary. If someone is bad the whole season, take note of that, and don't draft them next time.
