Need help to fix IP range

Hi, I’m New in Mikrotik
From online support I configure My RouterBord 750 as Hotspot and PPPoE With User Manager.
Hotspot IP is 192.168.88.1
PPPoE IP is 10.0.0.1

DHCP Network is 192.168.88.0/24

IP Pool
hs-pool-1 192.168.88.11/192.168.88.254
ppp 10.0.0.1-10.0.0.254

Now my all user take ip from 192.168.88.—
When they login in Hotspot it’s show different IP in status Bar.

How can I fix it.
Or How can I give 192.168.20.— and after login in Hotspot user Will Get 192.168.88.— IP in status bar
