I was able to get the scores to persist on screen. I also was able to add multiple measures to my list of notes without the program crashing, after a bunch of debugging. Currently, I was testing have different lengths for the measures and am having problems with the notes appearing on screen. I was trying to test changing x and width values but that did not work. The built in formatter in vexflow worked a bit better but my score and notes keep getting squished and cut off randomly.
