NodeMCU chip identification duplication

I installed a particulate air monitor. When I went to register it at this site stated that this chip was already registered. I checked Grafana and the reading from this chip Grafana started on 15 June 2021 at the time I installed this monitor. What can I do to register this chip when the sensor community site believes it is already registered. Is there an administrator that I may contact?
