Feeder ID issues / Incorrect feeder id

I’m experiencing a persistent JSON data issue with my feeder., I have attempted the following troubleshooting:

Restored original feeder-id.json files

Regenerated UUID clearly from scratch

Restarted services repeatedly

Despite these steps, I’m still seeing a JSON error at my old feeder.
How do I reset the feeder ID association to my original ID? On top of this I am having mlat issues.
