A variation generated using Text to Vector Graphic, Generative Shape Fill, or Generative Expand applied on the canvas is called a Generative Object, indicated by on its boundary. When you select a Generative Object, only the batch of variations it came from (linked variations) appears in the Properties panel. However, the Generated Variations panel shows all the variations generated in your document using these features.
You can generate similar variations, provide feedback, report, and delete variations from the Properties panel or the Generated Variations panel. However, the results of deleting variations from both panels differ.
