Monster Entity random walk around is very slow.

I have made a monster entity with high movement speed. I have set up basic mobs goals and everything works as planned, except for one thing.

When my entity walks around randomly just like most other vanilla living entities, the movement speed is way too slow, much slower than the movement speed attribute. But as soon as the entity sees a mob or a player to kill, the movement speed works just fine.

I have also made an entity that extends the vanilla zombie, and for that mob, it works just fine, the random walking uses the fast movement speed I gave the mob.

Any ideas as to why this happens ?
