Correct way to route the EXT in of the Digitakt into Ableton

Hi;

So i’ve used the hybrid setup for a long time but just noticed this weird routing:

I’ve got my DX7 routed into the Digitakt; and made a external instrument track to capture its audio as the inputs of the DT. But it is audible only in the Post FX track. Is that normal?
