Solved. Changed the section below in file /usr/share/X11/xorg.conf.d/50-synaptics.conf

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
        Option "VertTwoFingerScroll" "1"
        Option "HorizTwoFingerScroll" "1"
