I can’t add steps and the widgets are not showing up

Hello there!

Thank you for this great plugin. I currently have two issues with the plugin:

I bought the premium version but can’t add more than 3 steps. Everytime I add extra steps and save, it reverts to just the first 3 I made. How can I fix this?

Second issue is that I’ve added the filtering widget in the customizations page but it does not show on the modal page.

Screenshots attached for the second issue.
