World Download along with player progress

Hello, I have tried downloading our world so we can still play in on LAN without using an internet connection however after downloading the world and starting it as a singleplayer my character was reset that means 0 xp and no items. How do I download the world along with the player progress in it from our Aternos server?

Yes it is enabled because we have only the cracked version.

Nope, the world was not played in SP before.

My in-game name is Azeii, which is the same name when we play on the Aternos server however when I downloaded it and played on SP my progress went back to 0.
