It took me five minutes to work out that your three screen shots only show a single layer of the model!!!!! Very confusing...and not helpful.
Tahking your screen shots top to bottom....
The direction of the support is governed by the value or values in the Support Infill Angle field in settings.
The "gap" or missing layer is defined by the Upper Vertical Separation Layers setting......and has nothing to do with Auto-generation of supports
The direction of the infill on the first solid layer is defined by the value in the External Infill Angle Offset field in settings.
