Why can't the handle be deleted?

Hello, in custom cabinets and wardrobes, handles can be deleted individually, in multiples, or all at once, depending on your needs. Using a system cabinet as an example, the steps are as follows:

• Delete an individual handle: Right-click on the selected door panel – Handle– Click Delete.
  
• Delete multiple handles: Press Ctrl and click on the door panels with the handles you want to delete, right-click – Handle – Click Delete.
  
• Delete all handles at once: Right-click on the wall – All handles– Click Delete.
