So I just copy this into permissions.yml and it works? I have th esame problem. I justw anna disable that function for all OPs

EDIT:
Tried didnt work

Negate essentials.keepinv in your permissions plugin. If you use LuckPerms, run /lp group <group> permission set essentials.keepinv false.

If you use PEX or another outdated plugin, you should upgrade to LuckPerms.

I love you. Thank you so much i was trying that with another permissions plugin but didnt get it to work.
I have spent over 5 hrs trying to disable this in this in total
