Format View - On list load or refresh list all values disappears

Hello,

I have a list with with 9 columns, and I created a JSON formatted view which displays the list like this:

All is well if I make the "All Items" view the default view and then select the formatted view, it displays the result above; but when I'm in the formated view and do F5 all the content from the list disappears I'm stuck with the content that is uploaded by the JSON (example - "txtContent": "Equipa") and all of columns content is gone, even the images. And if I set the formatted list view the default view when a user enters the list all is empty also...?

Can someone help me? Thank you.
