Vapp = 135+25 = 160 (no further additives because of the large already increment), as you extend the LE devices according to procedure, the Slats will end up at 22° (middle extended dot) called "position 3"
ref: FCOM DSC-27-30-20 "A".
Your MAX SPD per the QRH table is 200 kts. For circuit, the procedure says not to change the configuration and fly @ -10 kt = 190 kt. That would be inside the red, because for "position 3" normally associated with slats = middle dot, flaps = 3rd dot, the barber pole indicates (according to lever position) 185 kt Vfe.
That might have to do with this?
