Amending 2018 fed return does not change state return (this cant be right..)

I am amending my 2018 return due to a missing 1099MISC while living in MD and prior to moving to CA in 2018. I can see the changes on my fed return and on the CA return (3 months out of 12) but not on the MD return (9 months out of 12). This can't be right...is there a way to reset everything?
