Vinyl setup troubles

Hello, I have decided to dust off my vinyl and Traktor set up but having some problems that I hope can be solved here.

My set up is as follows;
2 x Technics 1210 MKII
Thud Rumble TRX scratch mixer (Qbert Kickstarter 2014)
Traktor Audio 10
Traktor Pro 3 (recently upgraded from Scratch Pro2)
Mac OS 11.1 (Big Sur)

I have everything set up in THRU mode with Audio10 as the Audio Device and can get sound out through my system and see Deck indication of inputs however the indication at the top of the application (load, levels, time power) is not showing input at all.

Reason for my post is I was trying to record a mix as a test, recorder turns on however captures no sound which I suspect is due to the lack of main input levels.

To set up recording I have used Line for channel 3 and sent it to Input FX Send and routed to this in the Mix Recorder as External.

Any thoughts on what I have set up incorrectly, appreciate the assistance.
