On version 1.19.2, the item fire extinguisher can only extinguish fires that are directly pointed at and no nearby fires are put out
Changing the radius to 8 also doesn't fix the problem

I got this when using only this mod so it should not be a compatibility issue

Could you please let me know which version you are using like Fabric or Forge ?

It was on forge 43.4.2 with mod version 6.3.0
