Issue with graded environment and grade sync

[JNowellUF]

I seem to be having some trouble with grade sync and the graded environment. I have posted my Xourse .tex file at the bottom (with the graded environments commented out). It would seem that as soon as the first \begin{graded}{0} line is encountered, all future grading is obliterated, meaning that, as the file stands (with the graded environments not commented out), my students could only get about 29ish points of the total 50 available (set in canvas). I don't exactly remember the syntax of the graded environment, but I have tried nesting graded environments, and/or having everything in one graded environment or another but not nested, and it hasn't changed the result. I'm probably being an idiot here, so if I'm just not using it right, please let me know. As a note, with the graded environments commented out, everything appears to work fine.
