Help me with ALTERIA

Does anyone know why the texture pack (for the new map:) ) shows me that it is made for an older version, although I did the pack for both 1.16.1, 1.16.2 and 1.16.3 and my version was 1.16.2. Im begging for help. Without this pack, a new ALTERIA map could not be published. Thank you in advance.
