To my understanding they were not minted in 2022 but in 2018, 2019 and 2020 (3 coins each year).
2022 is just the year the package is being sold with these altogether and the year these were changed from non-circulating to normal circulating status. See comment already on the coin pages e.g. here.
NBU link gives the same info with minting years written on the package for each coin.
