No, that's correct (I'm a KS resident)--the DMV records show which licenses previously had the gender info changed, same for the birth certificate data with another agency.
The KS Supreme Court had previously ruled that changing one's gender on gov records had to be allowed, and this new law apparently does what's required to legally ban it again. While several other states also ban this, KS is the first state to claw back previously issued DLs and birth certificates.
BTW They sent the letters out on the 23rd and the law took effect immediately on the 26th with no grace period to allow people to comply, so they now do not have a valid driver's license.
Driving without a valid license carries a fine and possible jail time. There is no doubt they deliberately wanted to punish trans people who had changed their DL, by making it impossible to drive legally until they get a new DL, which takes time to process.
