Problems with new Titanfall patch

After the patch has gone through I have noticed a couple of problems.  

1st is the fact that every time that I am dropped from a match, I receive no XP and lose any challenge progress that I may have made during the match I was just in.  This is very frustrating especially when trying to regen or after completing the harder challenges.

2ndly is the fact that many times that I have played since the patch, I will end up playing the same level twice while in campaign.  This especially happens when I have a party of two or more of us entered into a match.  

Any advice or insight would be appreciated.
