Issue with analog lab software and keystep pro chroma track and midi channel

So i used to be able to use 2 or more instances of analog lab and have it squenced on its respective tracks of kstp chroma.
now the issue is since yesterday when I choose the keystep pro within the midi settings from the menu on the upper left corner (hamburger icon) and press ok this becomes disabled for some reason which this is not allowing me to sequence one or more instances of analog lab. I wonder if someone has the same issue and what is the solution? thank you so much
