How remove deleted Revisions from Dashboard

Hello, how can I remove the revisions (see picture) from the dashboard. I removed the backups (were just tests) but the revisions are still shown in the dashboard.

can anyone help me or is this a bug?

They should be gone after 30 days. If this doesn’t happen, you can directly edit the stats file (~/.duplicacy-web/stats/storages/storage_name.stats, which is a json file) and remove corresponding keys.
