Let's try adding it in there? Like so:
{"$id":"1","_systemStates":[],"_lastSaved":"2020-02-17T05:47:48.9728264Z","_resolutionIndex":7,"_gameTime":{"$id":"2"},"_textBanks":[],"_userIdentifier":"cc02246a-4002-4e9b-bb39-875f03163c50"}
It's real weird that the confirm button doesn't do anything, but maybe it's failing to change the resolution bc something about a vertical monitor is throwing it way off.
