Unknown inputs appearing in my daily data

Ive been a long time user of PVOUTPUT and had new solar panels installed last week. I have created a new system to start monitoring again and have put the old system into Inactive. The new system started uploading data sets on 24 Sep but a few days later a random input appeared for 16 Sep. Now a week later I also have an input for 18th and 19th of Sep has appeared. All three of these are before I even created the system ID. Could somebody else be inputting to my system ID?

Thanks.

You’ll also need to disable any scripts or Auto Uploading settings still pointing to the old system.
