This is an old house and pictures show the framing and joists around a stairway opening.
Compared to the “before” picture, you can see that the wood was removed from both sides of the double header. The ledger shown in picture #1 (before) was removed. Joist hangers were installed (pictures #2 and #3). However, the joists do not fully sit on the seat of the hangers. I believe the industry term is “not fully bearing” on the hanger seats.
Will this result in sagging floors or a structural failure? How should the contractor/framer fix this?
Edits 7/16/18:
1. Added “ledger” and “double header” (both are perpendicular to main joists) into the description of the problem.
2. Yes, there is a knot with a crack in the 3rd picture. What to do about it?
3. Would you suggest removing the new joist hangers and putting the ledger back in place (as it was in the first picture)?

Sorry if this sounds insulting, but that is terrible work.
Build a temporary wall underneath to hold the joists in place while this is being fixed.
Then remove the hangers, cut all the joist ends to 1-5/8" off the beam, stuff a new 2x behind, then re-apply the hangers. (Use plenty of long nails to attach the new 2x to the old beam.)
