Scheduled scans are no longer displayed

Hello everyone,
I have been using Avg File Server for many years. And a scheduled scan runs every weekend. Since the last update to AVG 23.7.2394 Build 23.7.8348.789 the scan is repeatedly removed from the planning and also from the history. This even sometimes happens while the scan is not running. Creating a new one several times also leads to the same error. The error was noticed because the last scan in the front GUI was supposedly 5 years ago.

Has anyone had anything weird like this before? Or is this a known bug?

thank you very much
