If I don't change Taoism setting, the offhand animation is working.
If I change setting like this

    S:combatItems <
        example:sword, 3.5, 1.5, false
        example:shield, 0.3, 0.6, true
        minecraft:wooden_sword, 3, 2, false
        minecraft:stone_sword, 3, 2, false
     >

The animation will not work when the offhand weapon is wood sword or stone sword.
