1. You iProperties indicates 2019, not 2018.
2. Post screen shot - this almost always indicates that you already have the part open in another window. (Your file works as expected on my machine.) Screencast would be best.
3. Why is your assembly a Mold Design?
I think I would have done this with Frame Generator.
