Service (BorgBackup) remains in the WebGUI although uninstalled

After I installed a plugin (BorgBackup) it can be uninstalled but does not disappear from WebGUI. -> Error when clicking 404 - Not Found "RPC service "BorgBackup" not found".

Remark:

• freshly installed system (no migration from OMV 5.x). Installation method: OMV 6 on debian 11
• no remains left in "config.xml"

yep, it worked thx!
