I have had the same thing happen on a 700. Check to see if the extractor claw lip is protruding its full length from the bolt recess.
If it is aways back underneath the bolt recess it probably doesn't have enough spring tension. You can simply slide the extractor around the side out of the recess and remove it, after its out, spread it apart a little bit.... keep in mind it is spring steel, it's hard and somewhat brittle, so don't break it, but it will take some force to bend, but if you do break it, they are under $20 and wasn't working before if it was setting in to far.
Mine was not springing out of the recess far enough and would just pull cases out of the chamber and sometimes drop them just outside the action port or sometimes flip them around and leave the case backwards on top of the next round to be fed.
