All those tags in the historian are there because there s data in the database referencing them, you would have to remove all the database references to the tags.

Historical tags never belongs to a project. If this would be from a database historian and you want to delete from the power chart, you can run a delete query over the sqlth\_xxx\_te table where retired tags are not null. For Edge Historian, you could try to open and edit `edge_historian.idb` file with [SQLiteStudio](https://sqlitestudio.pl/)
