Automatic Port Removal

We have an Adtran TA5K GPON system that we’re trying to set up alerts for and have run into an interesting situation. Whenever we provision a new GPON LibreNMS will pick up the new ports without issue. The problem we’re running into is that when the port gets deprovisioned and removed from the TA5K, libre holds onto it and just shows it as down. Is there any mechanism to automatically clean these up or will we need to purge these manually after each disconnect?
