is anyone else having problems trying to change or edit a form block?
When I click edit a modal window appears, but it only gives me an option to add fields, not to change ones that have already been created.

[Update]
it looks like the tabs that display the options were set to display:none in app.css. Not sure if that was something I inadvertently caused as I have been building out my own theme. But for now, I have simply overwritten the css in my own theme's styles.
