Hi experts,
Please check the screenshot why this double entry is showing. Please advice

It is because you have set an address-pool at either /ip hotspot or /ip hotspot user profile. Change both to address-pool=none. Setting an address-pool was intended to help device that might a static IP set in their setting be a able to still connect to the hotspot. That is no longer a common practice, so there is little harm in not using it. Clients will still get a dhcp lease from /ip dhcp-server and the pool used there.

i have already set to none but still same.
