iOS I didn't get the monster slayer hero achievement???(1.6)

[W31rdk1dd]

So I've done all the monster slayer goals but I didn't get any achievement no matter what I do, ive tried talking to Gill a lot, checking the list again, restarting(and reopening) the game, and try the next day but no luck, so if anyone knows what to do please tell me!(I know this may be a bit short but it's my first post here and i just need to figure this out so sorry!)

Protector of the valley is not an in-game achievement, so it’s not available on mobile.
