Touching build plate will make it so that only parts of the model which have absolutely nothing between them and the build plate get supported - so if your overhang is over another piece of your model, it won't generate support.
Could you please provide the Cura project file (.3mf, in Cura go to File > Save Project) so we can have a look at the model and your settings and try and figure out what's going on? For something like this a couple of screenshots really isn't much to go by.

Also if I change the Support Placement setting from everywhere to touching build plate, I face this problem.
