Ah that one.
That just relates to MY22 & OTA update. Which could well be 3 months old as some users have reported this showed in Feb update. And certainly none of the files listed show a April date on the below link.
But in true Kia style. No one is really sure what they are doing. 🤷♂️
This page gives the latest software (maybe) as it has been known for new files to be added with the old dates 😖 Just look for the 6 numbers in US date format.
