Harvesting issue

I’m setting up my server and i’ve got harvesting set to 5x
When i harvesting things it works as intended at 5x…

The issue i am having is harvest “life” how long it last when i “whack” at the animal with an axe or pick or any weapon… I’ve killed about 25mobs and maybe have gotten about 10 hide…Kinda seems there isnt a setting to prolong the harvest life or is there??

anything that i can do to help this or is this just how it is?
