Unwanted Text and Fill Patterns

[Zig]

When I import and CAD files and explode them I end up with text and fill patterns associated with the file. Inevitably I am left with text type and fill patterns leftovers in my project. I understand how to remove the fill patterns from my project library (though for some reason not all of the fill patterns can be deleted) but I don't see an obvious way of deleting text types which are no longer required? Is there a text folder somewhere, or is "purging unused" the only option? :?:

It is.
