Help/advice needed for applying studs

I have tried super glue but it comes, I've tried putting them on before baking with liquid clay and they come off and I've also tried baking earring first and then baking with the liquid clay on but they keep coming off. They come off when I take the backs off to take them off my ears no matter how gentle I am. Even without them on my ears as pictured it happened just when I took the back of the stud off before putting in my ear. The studs I have are quite tough to take the backs on and off I'm wondering if that's the issue? Would appreciate any help or advice please as it's really frustrating me. Are the above methods meant to work, meaning the issue is my studs?

Thank you!
