We are experiencing 'Request Error Percent' alerts that are not being cleared from the Open Alerts filter.
It has occurred numerous times alongside other 'Request Error Percent' alerts created at the same time yet this entry never gets resolved. It adopted the same status ('Critical' and 'Warning') yet contains no other attributes and looses its link to the component or source. Can manually apply 'Resolved' but it doesn't remove this alert from the open alerts.
We have monitor 2023.1 in a disconnected environment (hence no screenshot). This has been seen against server components and services on Win 2012 and Win 2019 machines.
