Trying to get items from list to display without repeating

I’m trying to make a list of breweries appear on a grid. I have nine squares. I want a list from 15 breweries to auto populate but not repeat. This is the closest I can get to with the code. I think I’m close, but not quite there (although I may be wrong). Attached is my code.

You need to remove the random item selected from the list of images, not from the buttons (grid)
