Reastream captures only left side audio in Cubase

Hello!

I have an issue on Cubase LE 7 where I want to use Reastream VST plugin to capture my monitored audio on another software (like OBS and such). This works fine but I only have sound on the left side (only in Reastream, it is fine in Cubase) and I don’t understand how it is possible to fix it? Every tutorial has it running fine from the start…

I use Cubase LE 7, Focusrite Scarlet Solo and Reastream stereo.
All my inputs are mono and heard/recorded as such in Cubase.
Both inputs (mic and instrument) are captured only on the left on Reastream.
