i am in a minecraft survival world. i made a raid farm that i was sitting at to gain xp, and after i went mining. when i started breaking blocks with my pickaxe i didn't collect any blocks even though i was breaking them. 

for example, i was breaking dirt with my spade and despite being in survival, there were no blocks to collect including the iron and cobblestone i was mining.

it was breaking blocks like i was in creative move but i have always been in survival.
