#3. Women's SmackDown Championship match
The women of WWE will already be represented at WrestleMania, since there are already two Championship matches officially on the card, but there are no SmackDown women set to be part of the show.
Paige's return last week on SmackDown was believed to be so that the Championship match could be set up as a six-pack challenge and include the like of Naomi, Carmella, Sasha Banks, Lacey Evans and the Women's Champion herself.
The match needed just one more competitor but since Paige was unable to travel to SmackDown last week, the angle wasn't included in the show and instead the company pushed forward the Women's Tag Team Championship angle, which also may not go ahead.
Bayley will be the only solo Women's Champion who doesn't defend her title at WrestleMania, but since she is the only women to defend her title in the Middle East, it may be the way that WWE balances out this decision and instead gives Bayley the chance to defend her title the following week on SmackDown.
