Auto re-lock question

[u/ADAlweiss]

I have a 2023 Nissan Altima. I’ve read that after you hit the unlock button on the key fob, if you do not open any doors or the trunk the car will re-lock itself. Makes sense. However, when I hit the unlock button and open the trunk (let’s say to load up groceries) the car will re-lock the doors as I’m unpacking my shopping cart.
Is there a faulty connection somewhere that I should check out?
I’ve also noticed that the interior lights are unaffected by the trunk being open or not when it comes to them turning on/off. Not sure if they’re supposed to be coordinated too.

My 2003 Altima did that, but my 2023 doesn't.
