Describe the Bug

Since Pangolin 1.12.0, I have noticed that routers/services are being recreated, but the old ones are not being removed, thus ballooning the count in Traefik. I first encountered this when I was first testing ee-1.11.0, and my Traefik got updated to v3.5.4. Back then, I rolled back both Traefik and Pangolin, and the issue resolved itself. I have had Traefik pinned to 3.5.3 build since the rollback and blocked the image from updating. Since updating Pangolin to 1.12.2, I am now seeing this behaviour again.

All the services with @file@file appended are not connected to any routers.

Middleware Manager:

Environment

OS Type & Version: Rocky Linux 10
Pangolin Version: ee-1.12.2
Gerbil Version: 1.2.2
Traefik Version: 3.5.3
Newt Version: 1.6.0
Olm Version: N/A

To Reproduce

Install Pangolin ee-1.12.2
Connect site
Create resource

You should be able to tell if this issue is happening easily using hhf's middleware manager.

Expected Behavior

If a router/service that was created by Pangolin is no longer being used, it should be deleted from Traefik.
