Issues after duplicating a Zero App: missing Content Filters and incorrect field references

Good evening,
I created a duplicate of an existing Zero App. After duplicating it, I renamed the copy and updated all the contents as needed.

However, I noticed two issues in the Edit Listing Page:

Content Filters do not display any fields to select (see image1.jpg), even though those fields are correctly present in the Single Listing Layout.

Some fields shown in the interface (see image2.jpg) still refer to the original Zero App, not to the duplicated one.

Could you please help me resolve this?

I will send you the access details through your support form.
Thank you,
Gianni
