I have some erroneous data which I want to delete so I thought I would follow the instructions on the weewx github file: cleaning up old 'bad' data. I copied my weewx database file to my Desktop and renamed it backup.sdb and checked it was the same size as the original. I then copied the instructions but got the following:
