Strange Figjam elements that can't be converted to components in Figma

I copied and pasted some irregularly shaped assets from a Flow Chart Diagram template file. These have circular shapes, polygons, etc that you can resize and work as if they had autolayout. But as I copy them into a regular Figma file, I can’t convert them into components. Not only that, if I want to add a frame to them, they jump out of the frame.

Any thoughts? Can I make them into components somehow?

Unfortunately, FigJam objects cannot be added to components in Figma design.
