Cannot add new assets/instances to frame

Everytime I add an instance from the asset community, it will not allow me to edit the size without removing it from my frame. Then, I cannot add it back into my frame to be used in my design. I am new to Figma and don’t see what the issue is. Could someone please help me troubleshoot this issue? I would like to add a screen recording, but this forum won’t let me since I am a new user.
