Style Standard Grayed Out. Symbol standard parasitic copy.

Standard Style, does not allow Purging style if the symbols are not deleted. I have tried changing layers, and copying symbols to another standard. The options are greyed out. If the symbol is copied to another drawing, then the style is created again... 

Style Library Manager does not solve this problem.

Autodesk Inventor 2020 version included.

Hi.  I believe this is as designed.  It is also true in AutoCAD that a block or style cannot be purged if there is an instance of it in use in the drawing file.

Thank You, for answer. Yes, I have been afraid of this answer. Hope there is a way around it. Just seem illogical to add invisible ID code to sketch lines...
