Havahart live trap cage - trigger not working

[HogHQ39]

I have an older havahart live trap cage and I’m not sure what is wrong with the trap. I believe the rod that connects to the trigger plate is supposed to be on the outside of the cage rather than the inside. The trigger won’t hold the gate to the proper height. I’m stumped… any info will help thanks. I have found videos for the newer havahart traps but none similar to this one

I don't know if it is the same . Yours is definitely different. I can get some better pictures tomorrow.
I think I have one like yours with the hook.

This one has the rod on the outside.

I have some inside and some outside. When critters get in them, they can really screw up the trigger.
Sometimes it takes some pretty good force to get things bent back where they should be.
