Maybe I did not explain it precisely, but I think you used flatten cylinder and in my file the circle has removed vertices ( add new circle and remove upper or lower vertices so the object get 'flat' ) and now try to put on the cube.

You can check cylinder from previously post and attached file -> it has 2 polygons / 8 edges and 8 vertices.

And here's the message I get:
