OBS doesn't recognise specific Line-In from Interface

Hi everyone,

I use a Focusrite Saffire 14 Pro and use it's sound in OBS as an Aux. I run a microphone XLR and a drum machine through the interface. The sound can be heard and seen both in the interface's monitoring software (where I assign the two fron mic inputs and the two line-in inputs at the back to individual mixer channels, so I can see that each input is working) and in FL Studio, my DAW, where if I assign an input to a channel, the sound comes through. Direct monitoring is turned off.
So when I mute a channel in the interface's monitoring software, then there's no sound on desktop by the mic/line inputs.

To the issue: In OBS I have an audio Aux channel which's source is the interface. I can hear both microphone inputs. In the back I have Line 3 and Line 4. The synth that goes through Line 3 can be heard in OBS but another synth runs through Line 4 and that one shows no sound.
When I check the interface's monitoring software Line 4 shows and plays sound. Also if I go into my DAW all channel 1-4 show and play sound.

How could OBS recognise Line 3 but not Line 4 when it's clearly working?

Thanks & peace
