World Sync corruption

I loaded my World that I last played today 3/20/21 onto my Xbox X. Before I loaded it I would play my world on my Series X and everything was fine. But when I loaded it onto my Xbox one X the old data from before I switched to creative and the new data after I switched merged together. However all the changes I made to the terrain and my house were reset to before I was in creative, and all of the new chunks and builds I added are now gone. Please help because I have invested too much time into the builds to go back and redo everything again.
