Gamepad Triggers don't seem to be working with Enhanced Input / Common UI?

Hello!

Long story short; I have an Input Action that triggers my Common UI buttons just fine with keyboard keys and most gamepad buttons, but once I switch the key to the gamepad’s Left or Right triggers, it completely stops working. I tested with two different controllers, and I have no other binding to the gamepad triggers in my IMC.

I presume this is similar to the D-pad being somewhat hardcoded for Common UI’s navigation by default (which I would also love to get control over). However, I have no idea what C++ class to even begin modifying for this, and I would rather not to, if possible, as I’m using mostly blueprints.

I’m using UE 5.4.4; Any help would be greatly appreciated!
