That's the default behavior. You can either delete the .mobi file or comment out line #367 in plugin.py.

from:

                    open(outmobi7, 'wb').write(mobisplit.getResult7())

to:

                    #open(outmobi7, 'wb').write(mobisplit.getResult7())

You can't change style settings with a style.ini file. (The plugin only checks the settings in kindlegen.ini.)
If you have problems with styles, you most likely didn't link the style sheets in Sigil via Link Stylesheets...
