So at one point I had accidentally turned off all additive camera movements. When I noticed I turned it back on, but now I don't lean passed people when I bump into them. I think it also disabled the screen shake when running with a weapon (there may be more I haven't noticed though). In the settings it says it's correct, same for the actual settings file:
"name": "AdditiveCameraMovements",
"type": "float_list",
"is_dynamic": false,
"value": 1.0,
"index": 2,
"default_index": 2,
"values": [
0.0,
0.5,
1.0
