Strange PV readings on Power Flow: ET112 configured correctly but phantom PV inverter remains

For as far as I can tell, my Cerbo MK2 seems to contain an incorrect device mapping. My Power Flow screen is showing strange values for the PV production. I am using two ET112 meters that should be assigned correctly — one as the Grid meter and one as the PV meter — but in the device list there is still a “PV inverter” showing up that supposedly works via an AC current transformer, even though that device has been removed from the installation for quite some time.
Does anyone know what could be causing this or how to fix it
