So I have been playing on my server and recently added a few plugins (Using Spigot) but soon afterwards I noticed that deop players got this message whenever they did basically anything such as move items, hit a mob, click a chest, and even eat a food item: https://imgur.com/XCikHBg
I only have the shopkeeper plugin installed however I have a downloaded structure called "The Tempest Box" or TTB on the world if that matters. Also, whenever I don't have spigot on and I am using vanilla MC the notifications do not appear. Please help it'd be really appreciated!
