Recorder not working

[mlbstrd]

OS: 10.11
Simple module pack version: (git SHA1 if builded from sources) 0.5.9
Module concerned: Recorder
Description: Followed the instructions - set left and right from some module outputs (which work fine going straight to regular outs), which is reading on the Recorder VU's. Set the destination which puts on the green light, arm the track and get the blinking red light, then whenever I hit record the red button switches off. Any ideas here? Literally can't get it to record at all
Steps to reproduce: As above
