Habitation Door Issue

[PhilandMena]

Advice please!
My habitation door is not fully secure at the top after locking.
Two pictures attached. One of door design and 2 the top door locking pins. The top pin as you can see is on some type of ratchet and when closed enters a metal bracket on the door jamb and rides up into position to lock the door. However, when the door is closed ad locked, if you push the top of the door from the inside the pin just rolls out of the metal bracket and the door opens a tad at the top. Still secure at the bottom and I suspect something has come adrift inside allowing the top pin to roll out of the bracket.
Has anyone any experience of this issue. If I could get a diagram of the door mechanism it might help my understanding of what is going wrong. The outside handle locks OK so I/m fairly certain something amiss inside.
Thanks in advance.

Right had a go at my door today, wasn’t too much problem to remove the door casing ( Trim)
Unfortunately the suspected broken spring was intact but can see that I had adjusted the bottom striker in too far so a easy adjustment will sort it out,
Have included pictures of the spring and locking clip, I have replaced the locking clip with a superior design that can be removed much easier if I have to revisit this job again, that’s the second picture,
Had to open the holes up slightly to get a easy fit,

Thanks for this. Can you clarify what you mean by bottom striker ? Pictures would be helpful too

Striker plate or some times called a receiver plate is the part of the lock attached to the door frame,
Not the door,
The two round bars on the door lock (top and bottom) go into the striker plate on the door frame,
Dark stopped play today but will take a pic tomorrow when I adjust it,

OK I've got that and thanks ! My striker plate OK and door pins enter without any issue and locate in correct position.

Feed back as promised.

Job now fixed and finding replacement springs was a nightmare. In the end the service technician could not get the door liner off as it was glued into position when first put together, So a small 1 x 1.1/2 inch hole cut into the liner near the locking pins and it took all of 10 seconds to fit a new spring and the locking issue was resolved. I have purchased a T.V. remote control holder which a, covers the hole and b, saves me hunting for the remote control in future, c, makes a super decretive job of hiding the hole and most importantly d, gives me easy access should I need to replace another spring.

Should you need springs you can get them from here. springsandthings.me.uk

Choosing right length, strength etc, is a mare but I have after trial and error arrived at this size winch works well for me.

6.3mm OD Tension Springs - 0.63mm Stainless Steel R0.47 Required Length 24 (mm):
(Choosing larger dia or thicker wire increases the stiffness/Tension, so choos carefully. The length includes the end loops too.
