Paywall display settings change not persisting in either browsers

Hello, I wanted to change the paywall display settings from the Paywall editor 

I wanted to include introductory offer values as well as variable preview values I had previously selected. When I select and save the second box (for introductory offer values ), it shows up on the preview but when refresh the page, the selection is gone and not reflected in the simulator. This behavior is same for both Chrome and Safari.
