custom css doesn't load

the most of the input in my custom css panel thorugh wordpress admin interface do not load.
instead, if I modify green.css or style.css all the changes I want to make take effect (so I guess i am doing right)

i still can just accept to modify the original files and suck later on theme updates but would like to figure it out a better way.
also included in custom.css doens’t work, maybe this is because it is loaded in the @import after green.css ?

i found contradictory opinion about the support or not of child theme with colorway, I will try also this way thou

did you get similar problems?
