lr-dolphin strange mapping problem

[pyramid_scheme]

I'm trying to use lr-dolphin on my arcade cabinet but my joystick isn't mapping to the control stick properly.

I've used the standalone Dolphin Emu and setup the controls in the gui – this works well but for some reason lr-dolphin is not working in the same way.

I've tried adjusting the settings in Quickmenu > Controls but I'm not able to locate the Control Stick mapping within those settings.

Here's a grab of the working config – any ideas how I can translate this to the libretro version?

Below is what I can see in the mapping options. I assume it's the left analog that needs mapping, but I'm unable to change those settings.
