Hi Roger,

Please check with Properties Inspector if the object in the 3-rd drawing is a Block Reference. I believe it is, and the contents of this Block was created on Layer "Structure", that is why you can see this object if Layer "Accessories" is turned off.

If you don't need Block - explode it with EXPLODE command.

If you need Block -BEDIT it in Block Editor and change layer of the object(s) inside block to Layer 0.
