Docker HUB still spams me about build containers

Even if I assured that my account is not configured to receive any notification about build containers one repository seems to produce them every day:

My initial intention was to be notified about failures but somehow it seems that it notifies me about successes and disabling notifications does not work at all.

My impression is that this is a bug with auto-test feature? Repository is configured with Auto-Test: both internal/external PR and repository links enabled.

Example subject: [Docker Hub] pycontribs/opensuse:latest: Build in ‘master:/opensuse’ (7356b04d) (OK)

Am I the only one affected by this issue?
