Getting MMTTY to TX in RTTY mode in SmartSDR

I can get MMTTY to transmit when using SmartSDR IF I set mode in SmartSDR to Digi-U or Digi-L BUT NOT if I set the mode in SmartSDR to RTTY. If I choose DigiU or DigiL instead, and use N1MM ... a click on the waterfall switches things back to RTTY mode and thus no transmit. I see instructional videos on the set up and they all show SmartSDR in RTTY mode. Any suggestions?
