Coop Protector of the Valley Achievement Bugged

[Plumsie]

I've been playing Stardew Valley Co-op with my mate for a while now. We have been working towards getting the Protector of the Valley Achievement and I've killed all the necessary monsters to achieve this achievement. We have no mods and the last thing that i killed was a Magma Sprite. The host himself did accomplish the achievement once killed all the monsters, however, i did not. The game is fully updated too. If anyone knows anything, or if i have to do something different to complete the task please let me know?

Is that checklist shared? I would think not, since you could be killing monsters 2-4x as fast... Did you check the checklist, and make sure they all have a star?

yes, i went into the adventure's guild and double checked. everything is completed and more :(

I checked my perfection tracker and it stated:
'monster slayer hero: yes'
so im not too sure whats going on? :(
