Score is Invalid

Hello,
I was working on a score, and saved it to the cloud. When I came back a couple of days later, I got an error saying the score was invalid. The only file that shows up in my scores folder is an older version (the first file I've attached). Strangely, it's title is Silver Bells 11/5 in the scores folder, but everywhere else it is Silver Bells 11:5. I looked in my application support folder and found the most recent version (the second file I've attached, titled not_uploaded_1.mscz) but I get the same invalid error here. Does anyone know of a way to fix this?

And I know that I should also be saving to my computer, I thought I had it set up so that it would save to both computer and cloud, but I was wrong. I have since fixed this.
