DHCP keeps granting recently freed IP leases

Hi experts,

I'm facing some issues with IP Theft under Cisco WLAN (Catalyst 9800) where some devices are receiving an IP lease from Infoblox which was assigned to a device that has been recently connected to the WLAN but it's not connected anymore.

Cisco C9800 has a customizable timeout to clear all information from previously connected devices, and if the IP address granted to a new devices matches that in DB from a previous device within that time (now I have it configured for 30 minutes following Cisco's BP), the device is not allowed to connect.

The problem is that when I check Infoblox for the DHCP on that range, there are some Free leases that has a MAC already assigned, and there are also some Free IP leases.

My questions, is there any way to tell Infoblox not to re-use an IP lease for a given time? Or to tell Infoblox to use Free IP addresses in a FIFO-like fashion and not something close to a LIFO-like fashion? Is there any way to tell Infoblox to clear the previosly assigned in a sorter time?
