How do I remove the Death Message text (and ideally also the "Items: 0 XP:2" part from the grave?

I tried setting all "text": [] blocks to empty strings or removing them, but that did nothing.
"base": { "icon": "minecraft:chest", "text": ["","","","",""] },

How to disable the GUI Interaction all together? I want the grave to not have any GUI, so a player may just break it to retrieve the contents. I thought the flag "enable_click_to_open_gui": false would do that. Is it bugged?
My current config:
config.json

It's all defined within model file
