All my account data is gone

So I was trying to log in to minecraft, I hadn't played in about a month or so. It was asking me to log in, but kept saying this pop up asking "Save purchases to a Microsoft account? Save to microsoft account (Or) Leave on device." I dont remember ever seeing this, but I remember that I always saved my purchases on my Microsoft account. Once I logged in, I opened up my worlds list and it was empty. Before, I had like 80 worlds. I started to freak out and checked on Settings, and checked my Global Resources/Packs. And like my worlds list, it said there were none of my packs, which I clearly remember buying several packs. I kept on logging off that account onto my other account to see if it was the same there, and then logging back into my main account. After about 15 minutes my packs are back, but all my worlds are still gone. I've never logged out, deleted the app, or anything.
