Looper consumer chain from JSON provider, only 1st reads

Hi team.
I have a layout as seen, container DIV as looper provider (JSON) and children DIVs per viewport.
Each child has a Headline element (H1) that consumes the value of the JSON, the main idea is not to edit 4 headlines, but 1 JSON.

[
{
“headline”:“Film Forming Polymers”
}
]

With this layout, I get H1 headline working and visible for mobile (1st in line as looper consumer).
{{dc:looper:field key=“headline”}}

However, the rest of the headlines read nothing, all checked and fine as far as I know.
