You connected online, so the console downloaded the list of available update versions for games. You don't get rid of this unless you replace the system save data at 8000000000000180 with a fresh one from a newly formatted system
No, "reset required version" in dbi will not fix this. Required version and available version are 2 different things
I'm not sure if deleting the save file will work and regenerate a new one on the next boot, or if you can use the file from someone else's console, but you can always do a full backup, format your switch, pull the save file, restore your backup, then inject the save file you pulled
