I was a bit frustrated that it didn't put them all in the correct order. Then I discovered how to solve the problem. I went through and renamed all my single digit weeks with a 0 in front of the single digit.
To rename your file or folder, click on the name to select the file and then click on the "More actions" button. That is the one with the three vertical dots. Then choose "Rename".
Once you do that with all your single digit files, you will have them all in order the way they should be.
