How to approach in-laws who still spell your kid’s name wrong?

My fil and his gf gave our oldest a card for her first birthday and they spelt her name wrong - Sofie instead of Sophie. At this point I’m feeling very frustrated because she’s four and we’ve had this conversation several times now with many of my in-laws (because somehow my family manages to not routinely spell our daughter’s name wrong, it’s almost like this isn’t something that should be hard to do). They all see us call her “Sophie” and “Sophia” and “Soph” on Facebook, through texts, literally everywhere and yet it’s still happening. At this point it feels intentional since I know they didn’t like that we chose the “ph” spelling over the “f” spelling. Anyone else have experience with this?
