After killing zombie pillager won't stop shooting arrows

I build fencepost where villager where shot by pillager, the villager would fall down. I created over 20 pillagers, when they shot the villager down, a zombie tries to kill the villager, after The zombie get shot and start attacking pillager. When villager where dead pillager attacks the zombie. of course, zombie died, but pillager kept shooting same way when they were shooting the zombie.
