I tried resizing the table and scrolling the table to the left, then updating my shared view, which seems to have worked for me.

One thing I noticed is that this is a huge CODAP file (60 MB). Given there are only 30 cases this must mean the geoJSON boundary definitions are extremely detailed. If you have the original geoJSON file you might try using MapShaper to reduce the complexity of the boundaries, greatly reducing the size of your CODAP file, and the time it takes to load.
