Fix your NAS so that it sends the correct accounting packets.
FreeRADIUS *assumes* that the accounting information in SQL is correct. If the NAS doesn’t behave properly, the data in SQL will be wrong. And the server will assign duplicate IPs.
Until you get a real NAS (or fix your current one), the best solution would be to write a script to read IPs from SQL, and then scan those in the network. If there’s a response, update SQL to mark the IPs as still in use.
