I downloaded my worlds folder and upload on singleplayer minecraft but my progress is all gone

Hello, if you are reading this. So I've been playing a new server recently with a bunch of friends. We built quite a lot and has made decent progress. Because we are a building server thingy I wanted to save a copy of the world in single player so I can planned my base in creative. So I downloaded the world (unzip it too with winrar) and then upload it to my worlds folder in single player. After teleporting to the right coordinates, I saw all the terraforming and building I did was gone. Is there anyway for me to download my world with all the progress? (not the items more so the changes I did to the world) Thank you so much for reading.

P.S I set it to cracked because one of my friends used a third party cracked minecraft, so can that be the thing causing these problems? Thank you once again
