Unable to update my Resort in the Steam Workshop

So I got some progress done in my Resort yesterday, and before calling it a night, I wanted to update my Resort in the Steam Workshop with all the new progress I’ve made. I went to “Update Existing”, but my Resort wasn’t there but the message “No uploads found”. Even clicking “Get Uploads”, it’s not showing up.
I checked my Steam account just incase I pay have deleted it by accident, but it’s there. Even restarting the game, it still doesn’t show up, and I get the same message.
