Never had a latch issue on either of mine. One ham fisted operator kept dislodging the inner door release on the cross tube. Ended up cross drilling the pivot and installing a machine screw there.
So, either the weather stripping is displaced (as suggested above), the door is out of alignment (bent), the striker needs adjusted, the latch is damaged/ fouled, or the cable end for the inner door release is kinked at the latch end.
The door has two stages, almost closed, and fully closed. Sounds like you aren't getting either stage. I'd start by removing the latch cover plate and ensure that the release cable isn't too taut. I can't remember where the adjustment for cable tension is, but, I think it's under the latch cover plate. And, I believe the inner release handle can be slid a little fore and aft by loosening the torx screw.
