Ores working with fortune

I came back to my base after doing some mining. I ended up using silk touch to mine all of the ores in order to conserve space in my inventory. I placed down the coal and diamonds I'd found to mine they with my fortune 3 pick axe (Netherite). For each piece of coal and diamond ore that I mined, I only record one piece back, for over 3 stacks in total for the ores
