Deleting old datapoints

[klausiob]

There are some warnings like "xxx is present in the database but missing in the datagram from Gardena cloud" because some properties are generated under a different ID from gardena. How can I delete the old data points without having to delete all of them? Data points under delete objects only works on the surface, warnings remain and become visible again when new data points are created. Can I delete them directly in the database?
