Comment 1 for bug 1637881

Hi Gabriele,

Thanks for the bug report. Unfortunately I can't do much to fix this problem. It is a system bug and affects every application which use the circle on the home screen. I reported that long time ago but sadly with no effect. See bug #1458336 and bug #1458335

You can manually try to remove the info. I never did it myself so I can't confirm if it works. But this is what one of authors of user metrics (data in the circle on the lock screen) said:
"the database lives in /var/lib/usermetrics/usermetrics6.db and the schema is reasonably straightforwards select * from "usermetricsservice::datasource"; to figure out the ID of the data source you want to remove then purge the related data for that userData_id from "usermetricsservice::dataset" then remove the entry from datasource.
Alternatively you can just remove "usermetrics6.db" file but then all your statistics will be deleted."
