Tkinter Buttons Created in a for loops but can't reference data

I have a tkinter project i'm working on. The end goal is to have a Window appear that has all of the data in a json file appear as individual objects (either a button or next to a button) that can then be clicked to have the data altered and saved back to the json file as well as an option to add new levels.

What makes this complicated is that because I'm making it "future proof", i have to create the buttons in a loop, so their names are not defined for me to reference later. I've tried using cget(), passing them through a validation in tkinter, v.focus_get(), and none of them come up correct. For a second i thought that .grid() being on the same line might make me reference the grid object, while not wrong, changing that did not fix the issue. Using cget() gave me "." as whatever information i try to pull.

I'm not married to my formatting, it can be a pop up window, through text boxes, i just don't want to put it all in a listbox with all of the information where someone could then mess up the json formatting I will simplify the data in the json file and code below.
