Hustle Not Saving Custom Content Options

I'm trying to set up a Hustle Custom Content box that is activated on a Click trigger.

I created a new Custom Content.
I go back to edit it and it did not save any of the Display Options.
If I try and edit anything about it, the saves are not saved when I click on Edit again.
If I try and change the Pop Up activate/deactivate, it doesn't get saved.
It shows up on the Hustle dashboard, but does not show up under settings. (Not sure if it is supposed to)
